I ended up starting my period April 20, 2020 (same day I got the vaccine) and it was the heaviest cycle I've had in years. I went through several tampons in a day for about a week til my period abruptly stopped on April 26, 2020. It started about 2 hours after the vaccination. I usually don't cramp but I was having problems sleeping because of how bad it got. I was also more bloated than my usual cycles. I dealt with extreme fatigue, I slept a lot that week and I did the bare minimum that week at work (which is unusual for me). I also don't usually have mood swings but I felt like my hormones were a bit intense to the point I kept snapping at people even though I like to think of myself as level-headed.

1st shot - Mild reaction to first shot, itchy everywhere. 7mins after injection. Taken to ER (shot was down at local hospital) and given some antihistamines and felt fine afterwards. 2nd shot - No reaction right away like the first one, migraine for 2 days, went away. Main concern though is that my period is currently 2 weeks late after I received my second shot. I have taken multiple pregnancy tests and they all came back negative. Apparently a bunch of my friends have had the same side effect but they told me it comes back after a month. I?m surprise that this isn?t listed as one of the side effects of the vaccine. I was ready for the side effects listed but when I haven?t had my period I was worried and didn?t realize other women were having this side effect also. I feel this should be told to women in order for them to prepare that this could be a side effect. Also it?s not just me, apparently there?s been a ton of woman about it on the internet talking about it and many of my personal friends have the same experience. Please be more open about side effects with women?s bodies.

My last period started Tuesday Feb 2nd and did not stop until 14 days later, more than double my usual menstrual cycle. It seemed pretty normal and painless, but then on 8th day I was surprised to find myself still bleeding . It was a darker color around then, but then became brighter and I noticed myself passing clots when I went to the restroom that were loose, but about the size of a quarter or half dollar. I did not bleed through any menstrual pads, but the return of bright red after it being a darker red that im used to at the end of a period had me concerned. I was in slight discomfort around my uterus/bowels and I couldn't tell if it's my body recovering from the vaccine, or something else. I received my second dose of the COVID-19 vaccine 2/11/21 (Pfizer) and stayed home from work as I had a fever/headache/chills (this was not unexpected to me, my coworkers had the same symptoms). Family medical history: grandmother (dad's mom) in remission from stage 4 uterine cancer about 5 years ago. Mom had endometriosis at 45 and had a hysterectomy.

At time of vaccine (04/07 11:45 AM) was light-headed and had shoulder pain at injection site but no other adverse effects during observation period. While driving home, had some tingling/numbness in left arm and knees with persistent pain in shoulder. Felt fine other than shoulder pain and slight headache until that night. I went running after finishing work (around 7 pm) and started experiencing intense tingling/numbness all down left arm to hand as well as intense knee pain not typical during running, at which point I stopped running and went home. When I got home I noticed my left index finger had lost circulation (was white). That night I experienced moderate but increasing fatigue as well as chest pain and tightness. My hands both felt numb like they fell asleep/lost circulation, as well as my left arm and feet. The next morning I felt better but the fatigue and numbness in my hands and feet started up again around 10 am and lasted for several hours. I had some chest pain that night (around 11 pm) and a headache on and off throughout the day. Today (04/09) I felt completely fine. I did start my period the day before my vaccine (04/06) and was having heavy bleeding/cramps that day and a bit throughout the time described above.

After receiving the second dose of the Pfizer COVID vaccine, I had severe flu symptoms (chills, nausea, body aches, cold sweats, migraine, fatigue) starting about 7 hours after the injection and lasting for approximately 20 hours. The evet that I was primarily concerned about was that, about a week after the vaccine, I started my menstrual cycle and got a period. My IUD has prevented me from having a period for 2.5 years, and so it was alarming to get one suddenly out of nowhere. While this was obviously not a life threatening event by any means, I wanted to report because of how unusual it was so that if other women are having this experience (or any changes in their menstrual cycle) there will be appropriate documentation to list it as a side effect, and help alleviate anxiety by informing women this is a possibility following being vaccinated.

Once my period started, (somewhat on schedule) I had terrible period cramps. Worse than I've ever had before. I very rarely get cramps at all, and these were certainly the worse I've ever had. Pain was bad enough to prevent my ability to work and to some extent move at times. This is not something I have ever experienced before. Reporting because I have heard anecdotally from close friends about changes in their periods after the vaccine as well. I had not heard of this until after I was already done with my period, so it wasn't something I was expecting or in my opinion not placebo related since I did not hear about possible period-related side effects until afterwards.

I have never lost that much blood menstruating in the past, and at one point I briefly passed out due to the combination of fatigue and weakness from the blood loss.

The cramps experienced were nothing like my normal menstrual cramps, I was doubled over in pain. And on the third day after the shot, I bled for the first time in 2 years (since getting an IUD). My breasts also doubled in size and extremely painful.

At that point, I briefly passed out and collapsed into the bathtub. This has never happened before in my life.

To, The Centers for Disease Control and Prevention The patients. I am a 27-year-old female residing since August 2019. I am a Resident and an immigrant. On the 20th of April, 2021 I took my first shot of the Pfizer-BioNTech COVID-19 vaccine in where I reside. After 48 hours of taking the vaccine, I started experiencing extreme fatigue, dehydration, and chills. I also registered a fever of close to 101 on a few nights in the week after. I thought this was a temporary side-effect of the vaccine, but the side-effects persisted and was not dying down. Over the next 2-3 weeks my health condition waxed and waned. I was facing extreme fatigue to the extent it had disrupted my normal life, heavy dehydration, loss of appetite, feeling cold easily, especially in the evenings. I called up the center and asked if I could delay my 2nd COVID-19 Pfizer shot, but because it is generally advised to take the second shot within a 28-day period in the United States, I decided to go ahead and take my second shot on May 14th. I took a couple of Acetaminophen tablets this time to help reduce a possible fever. Over the next weeks, my condition did not seem to change, even though I was done with both my shots. I continued to face fatigue and weakness, I had lost 10-11 pounds, a huge loss in appetite, I started noticing heavy hairfall daily. My period had not come since taking the vaccine. In the early month of June, I noticed dark red blotchy marks that had appeared on both my arms. My health started deteriorating heavily in June, there were days when I could sleep all day. I started noticing a fever which climbed to 101-102 daily, especially in the evenings and continuous shivering. Seeing the signs of a serious medical condition, I filed for emergency leave from my workplace and decided to fly back to India where my family resides. I landed in the 30th of June, 2021. I was admitted to a hospital in the Emergency Unit on the very same day and where I continued to remain hospitalized until the 9th of July. I was hospitalized for a period of 10 days, during which multiple blood tests, scans and procedures were run on me, at the end of which I was diagnosed with now having a chronic illness, an Autoimmune disorder called Systemic Lupus Erythematosus. I am currently, recouping from my illness and undergoing treatment for SLE. I do not know if there was a correlation between my taking this vaccine and the triggering of my illness, but if there is a possibility of the vaccine triggering an Autoimmune disorder in healthy individuals, I would like the concerned authorities to make a note of it. Symptoms: Extreme Fatigue, Continuous High Fever, Heavy Hairfall, Loss of Appetite, Feelings of Nausea, Red marks on arms, Weight Loss, No menstruation

I was exactly 4 weeks pregnant at the time of my second vaccination. On March 23 I started to develop cramping in uterus. On March 25 or March 26 (I cannot remember exactly which day here) I started spotting, and then by the next day I was bleeding. On March 29 I saw my OBGYN who diagnosed me with a miscarriage. I continued to bleed for approximately 10 days, as well as dizziness, and feeling very faint. I have had 2 very healthy pregnancies in the past and no health issues. This could be absolutely unrelated, as early miscarriages are almost impossible to pinpoint, but I did feel this should be reported for researching purposes.

Within 7 hours of receiving the vaccine, I started what I thought was my second period of the month. I had just finished a period 12 days earlier. I am usually 35 - 42 days between periods so this was VERY unusual for me. I had my normal period pre-vaccine Jan 4 - 9 then 7 hours after the vaccine started bleeding again from the 21-25 of January. Then again on Feb 4 - 9. I got my second vaccine while bleeding. Then again started to bleed on Feb 21 - 25. I had a doctors appointment at the end of February. I got an annual gyno exam as well as a ton of bloodwork was taken to check everything out. I was told to continue to monitor the bleeding and if it didn't stop we would do a pelvic ultrasound. Well, it didn't stop so we did and it came back normal. I had a mostly normal March with light bleeding. I thought perhaps it was getting better but no. I have had two periods in April. In fact still bleeding on round two and this is my 6th day bleeding. Periods or irregular bleeding was April 12-17 and then again on April 24 - 29 (still happening and it's the 29th). This is very scary to me as no doctors can help.

My period this month was April 15th-April 21st with no additional spotting/bleeding after the 21st. Within 24 hours after the first vaccine, I was bleeding enough to need a pad changed every few hours. I experienced all symptoms that I typically have during my period - uterine cramping, lower back pain, & a loss of appetite. After 48 hours, the bleeding has stopped and I?m no longer having symptoms similar to a period. I?ve had an IUD for over a year & have never had break through bleeding or spotting. Additionally, this was heavier than slight spotting - it felt as if I had started a new period.

I have had a very predictable, regular, 29-day period cycle for the past 1.5-2 years. I track my periods every month. After receiving the vaccine, I got my period 5 days early and had heavy, painful period symptoms that are normally mild for me.

I have lost a lot of weight, about 40 pounds. I was having migraines pretty much every day. I also started to get on one side of my face, left side. Then the same started happening to my right leg. I started to have vision problems, where me the sides of my eyes would go black and cracks in my vision. I went to the neurologist, ophthalmologist and no one had been able to figure out what is wrong with me. I have not been able to work for months. I was pretty active before the vaccine, I worked with a cancer institute for kids, but now I could not perform my daily activities, got so sick all the time. I had to move back with my parents.

I've had blood panels done, eye exams, MRI of the brain and pap smears but the exams are all negative and can not find the reason to my symptoms. No spinal tap yet done. Also my asthma is not under control and I get winded when going up a flight of stairs. I do not have the lot# to provide today.

Developed acute-onset, sharp right pelvic/groin pain radiating to right groin and flank the day after receiving first Pfizer COVID vaccine. Non-contrast CT abd/pelv revealed right ovarian cyst which resolved on follow-up vaginal ultrasound 1 week later. Within about 2 days, the sharp pain progressed to burning neuropathic-type pain across the pelvic/pubic region and down bilateral inner thighs to knee level. Pain was constant. After 10-14 days, the pain transitioned from burning sensation to sensation of feeling cold (both on skin and deep tissues) that would feel normal to the touch. It is symmetric on both sides and begins at the level of umbilicus and involves both groins and medial thighs. Symptoms worsen with sitting or standing up for prolonged periods of time (and become more noticeable/bothersome) and as the day progresses. About 2 weeks later, the severe burning pain progressed to include bilateral buttocks and outer thighs as well. MRI brain/cervical/thoracic/lumbar spine largely normal (tarlov cysts S2-S3, small left disc protrusion C5-C6). CBC, BMP, TSH, B12, B6, lyme titer, ESR normal. Currently being treated with gabapentin 300mg TID.

Amenorrhea - Lost Period - No bleeding Have not had a period since 02/28/2021 I was vaccinated on 04/01/2021 and was supposed to start my period on 04/03/2021. It never came. I am not pregnant. I am currently in birthcontrol and have never missed a period. I am unsure if the vaccine affects birthcontrol or fertility or how long it will cause amenorrhea. I was told to ?wait another month and see what happens.? This was not caused by stress, diet change, weight gain, pregnancy, etc. The only thing that changed in my life was the vaccine. You need to investigate this association with blood clotting in women of childbearing age.

My menstrual cycle was late by 2 weeks and I had the most *severe* cramping of my life. It began at 5:00 am with low to moderate levels of cramping. By 6:30 am I was fully awake and waiting for the local CVS to open at 8 am so I could purchase ibruprofen. (I NEVER have to take ibruprofen due to cramping). I ate food before I took 200 mg - an hour later my symptoms had progressed to include doubling over in pain and nausea at which I ate a little more food and took 400 mg more (total 600 mg). At 600 mgs my symptoms abated enough for me to eat a small breakfast (10 am). 4 hours later the nausea and severve doubling over with pain cramps returned which is when I ate more food at took another 600 mgs of ibruprofen. I went to bed at 7pm that night (usual bed time is 9:30) I used ibruprofen to manage my symptoms all that first day ? the next day I was exhausted from feeling so beat up the day before but thankfully no more cramping or nausea. Today is day 3 and I am feeling back to myself. I would just like to reiterate that I have NEVER in my life had a period this severe in cramping or nausea.

Until now, she said she is still experiencing dizziness, waves of nausea, tiredness, and chills. She said she feels hot and cold a lot. Last night (14Apr2021), she said she had cramps similar to that of menstrual cramps. She said she has not had cramps ever since she started being on an Intrauterine Device (IUD) and birth control. Consumer also said that she experienced Vaginal bleeding last night (14Apr2021), when she is not even scheduled to have her menstruation yet. She wants to know if this is a normal reaction to the vaccine, and if it is normal that she is still having the symptoms even after almost 7 days since receiving the vaccine. Caller states she gets dizzy a lot, waves of nausea, and felt like she had a fever, hot flashes or cold a lot. Had to call out of work on the weekend. Last night was really weird for her, was having cramps, like menstrual cramps, has an IUD and takes birth control and went to the bathroom and she was bleeding, even if she was supposed to have her period it wouldn't be the time she was supposed to be having it, called her Gynocologist to let them know. Dizziness gets worse during the day, nausea comes in waves, tries to sleep through the day, the more she sleeps the better she feels. Does not know if this is an allergic reaction. Outcome of the event was unknown. No follow-up attempts are possible. No further information is expected.

Extremely heavy irregular periods in between my normal periods. Menstrual cycle is typical 28 days. I am having very heavy periods starting 13 days into my cycle that lasts 7 days. Also having periods when I should be at the 28th day of my cycle. So essentially I'm bleeding every 13-21 days. I am on Junel birth control which I started (04/24).

Sore arm starting the evening of the first and second shots and then fatigue the next day. These side effects are not concerning and not a big deal. I did want to report that my menstrual cycle had a ?double peak? ovulation and a resulting very late period (3 weeks late). I chart my cycle extensively and this has never happened to me before; the only change during this cycle was the second covid shot close to my typical ovulation time. I know that stress and illness can cause a double peak (meaning ovulation is delayed), so I believe this shot may have been interpreted by my body as an illness as I was not under stress or sick at this time. I did not have an issue with my cycle during the first shot. I felt this was important to report as I had only heard of women having early or very heavy periods after the shot.

I had had my period when I got my first shot, around 2/27/21. I thought it was weird when two weeks later, I started to get "another" period, when I'm on birth control and my period is always normal. It started early in the morning on 3/9/21 which was my birthday. I started having such horrific cramps, that they felt worse than contractions. Eventually, I was losing so much blood, that I was worried if I stood up from the toilet, that I would pass out. I waited until my Dad came home around 4 p.m., and had him drive me to the emergency room. I was in horrific pain, losing a lot of blood, etc. Eventually, I went to the bathroom, and passed what was a fist size piece of tissue. It looked almost like a clear/bluish flesh, the size of an old rubber coin purse, with a thick and malleable consistency. The doctor at the emergency room never did an ultrasound, vaginal exam, etc., but said that I had a "dysfunctional uterus". This had never happened to me before, and I had never passed this type of tissue. The fact that it happened exactly 2 weeks after getting my first shot was weird. Then, 2 weeks after my 2nd shot, it happened again. The same thing. I had a period that I was not expecting, and ended up passing a fist size piece of tissue. I had contractions all day, almost passed out from the pain, until that was passed. I'm not sure what is going on, but it definitely seems related.

I received first dose of Pfizer vaccine on 4/12/2021 and second dose of Pfizer vaccine on 5/14/2021. At the time of first dose, I was not pregnant but we were actively trying to become pregnant. At time of second vaccine, I was pregnant (possibly 1-2 weeks along). I did not know I was pregnant. At my regular first check up on July 6, 2021, I went in to confirm pregnancy with my OGBYN. An ultrasound confirmed I had a blighted ovum, which is a type of miscarriage that the body does not recognize on its own. I did have a surgery to end to miscarriage since my body did not do it naturally. I wanted to report this happening in case it was significant since the timeframes of receiving vaccine and pregnancy were very close together. I know tests on the safety of this vaccine have been very limited and wanted to offer my experience in case it is relevant. Thank you,

I started my period about a week later and experienced much heavier flow than normal in a much shorter period of time. My second dose was received on 01/20/21 at 10am at the same facility. The day after I began similar feelings of cramping and experienced very heavy, opaque white discharge from my vagina with a couple of pea sized clumps of what looked like my vaginal wall the day or two after, but then none at all. I continued to see this odd discharge until today (01/31/21). Neither experience was at all painful, but it was very alarming.

I am unsure if this is related but thought I should report it because it was highly unusual, but: My menstrual cycle began at around 12:30am on 03-19-2021. There was some bad cramping as is usual for me in the first 24 hours. I was able to function normally enough until about 9P (on 03-19-2021), at which time I began experiencing debilitating cramps and muscle spasms that made it difficult to walk or move. I felt lightheaded and like I was going to pass out (which has never happened related to my period before). I got in bed and this persisted until moving at all brought me to tears. I have not been in this much pain from cramps and muscle spasms in over a decade. And never this prolonged and intense. I was unable to sleep until about 4:30am, managed to sleep for a few hours, had to see, and now I'm here filling this out before I attempt to go back to sleep. My pain at the moment is high, but similar to what a normal "first day of cycle and it's bad" day would be for me. Before this, though, was 8 hours straight of some of the worst pain I've ever felt in my life. I felt it important for me to make a formal report in the event that adverse effects surrounding menstruation were common for others and in case this does not subside. I am thinking it will like the initial muscle aches after receiving the shot.

Early miscarriage; This is a spontaneous report from a contactable other health care professional (Patient). A 30-year-old female patient (pregnant, last menstrual date 19Jan2021, Delivery date: 26Oct2021, Gestational period 4 weeks) received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number EL9269), via an unspecified route of administration on right arm on 19Feb2021 at 15:15 at the age of 30 years old at a single dose for COVID-19 immunisation at hospital. The patient's medical history included rheumatoid arthritis. There were no known allergies. Concomitant medications included prenatal vitamin.

Since the vaccination, patient was not tested for COVID-19. The patient was recovering from the event. No follow-up attempts are possible. No further information is expected.; Sender's Comments: Pending the limited information on clinical course, the company does not attribute the event early miscarriage to BNT162B2. The detailed document of pregnancy, relevant risk factors, status of rheumatoid arthritis are missing for a medically meaningful assessment. The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events.

Vaginal bleeding/irregular bleeding; bloody noses; spotting; This is a spontaneous report from a contactable Nurse (patient). This 30-years-old female patient received at hospital bnt162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE), dose 1 administered in Arm Left on 17Feb2021 (Batch/Lot Number: EM9809) as SINGLE DOSE, and dose 2 on 07Mar2021 (Batch/Lot Number: EN6206) administered in Arm Left as SINGLE DOSE for covid-19 immunisation. Age at vaccination 30 years. Medical history included ongoing spotting (she has had her tubes tied in the past /She continued to have spotting even after the period was over). The patient got 1st dose on 17Feb2021 and developed Vaginal bleeding, bloody noses. She said she was having a period every 2 weeks, and "spotting" every other day. The she got 2nd dose on 07Mar2021, and experienced nose is bleeding and vaginal bleeding again.Then it was added she completed both; and keeps having irregular bleeding. she received the first dose of the Pfizer COVID 19 vaccination 17Feb2021 at an unknown time in the left arm. On that day she noticed irregular bleeding, spotting. Mentioned she has had her tubes tied in the past and so she called her gynecologist who made an appointment for her. Then she got her regular period two weeks later to she cancelled that appointment. She continued to have spotting even after the period was over. She mentioned this to her gynecologist twice and he said to wait and see. She received the second dose 07Mar2021 at 16:50 PM in the left arm. She noticed today on 10Mar2021 she was having vaginal bleeding and spotting with bright red blood and also a nose bleed. Mentioned she also noticed blood with sex. She was concerned and plans to contact her HCP next because her brother had osteosarcoma at 16 years old and she has a cousin who had thrombocytopenia. Seriousness criteria provided -Other medically important conditions. The outcome of the events was not recovered.; Sender's Comments: Based on available information and known drug profile it is unlikely that the reported "vaginal bleeding, spotting with bright red blood and nose bleed" were due to bnt162b2. These are probably intercurrent medical conditions. Case will be reassessed of additional information is received. The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events. Any safety concern identified as part of this review, as well as any appropriate action in response, will be promptly notified to Regulatory Authorities, Ethics Committees and Investigators, as appropriate.

I had my first dose of Covid 19 Pfizer vaccine on the 5th of April, 2021 at 1pm. I had sore arm and was fatigued which was expected. However, the day I had my vaccine was also the day my menstrual cycle started and just to assure myself I informed the pharmacist and asked if that was okay and they said it shouldn?t be a concern. I was doing fine until toward the end of day 3. I was expecting my period to stop as it always does on 3rd day but I started bleeding heavier that day there after. It didn?t worry me much until I started discharging huge blood clots as big as an apple 2 times every after 30 mins from that moment. I rushed to the ER later that night(still bleeding heavily with blood clots every now and then) but I was not admitted since my vitals and the blood counts were normal at that moment. I went back home and hoped the bleeding would stop but again with on pain or fever what so ever I kept bleeding all day. This is my 5th day of bleeding. Then on Sunday morning, I still kept bleeding heavy and I was too weak that I went back to the ER again. This time , (day 6) I got admitted because I have had lost a lot of blood and I needed blood transfusion. My HB dropped from 11.3 to 6.7 and it went further down to 5 something. I got 3 units of blood transfusion in the ER. They did ultrasound, CT scans(with and without contrast) and still couldn?t figure out the cause of the bleeding. My uterus showed no problems but my body was not even responding to Tranexamic acid to stop the bleeding. So the doctor proceeded with an angiogram and did an emergency uterine artery Embolization to stop the blood supply to the uterus. The bleeding stopped there after and I started regaining my vitals. However, the cause of the bleeding still remains unknown.

My period is 6 days late. This is not normal for me and nothing else has changed in my life since my last menstrual cycle. My period is incredibly predictable and it is physically impossible that I am pregnant. I took a pregnancy test just as an extra precaution and it was negative. I have been seeing news reports of women indicating that their cycle was disturbed by the vaccine and until it happened to me, I questioned the veracity of these claims. However it has now affected me and I believe that the vaccine is the cause. I do not know if this constitutes an adverse event but since it is a side effect that is not listed on the CDC website, and since it is affecting my physiology, I believe that it should be considered seriously.

Miscarriage. I was 5 weeks pregnant at the time of the 2nd Pfizer COVID vaccine on 4/23/21. On 4/22/21, the pregnancy was confirmed by Ob/Gyn through a blood test, urine sample, and ultrasound. I was at the time and am a healthy 30 year old woman without pre-existing medical conditions or any conditions that would put me into a high-risk pregnancy category. The estimated due date was 12/20/21. Received 2nd COVID on 4/23/21. At 3:30pm on 4/28/21, I began miscarrying the pregnancy. On the same day at 4pm, I was at Ob/Gyn and they confirmed that the pregnancy was likely miscarrying through an ultrasound and blood tests. IMPORTANT: On 4/28/21, the pregnancy measured exactly the same in size as it did on 4/22/21. In other words, the pregnancy either STOPPED growing the SAME DAY it was confirmed or the EXTACT NEXT DAY, which was the day I received the 2ND COVID VACCINE. I discussed with my Doctor wither to proceed with the 2nd Covid vaccine and it was suggested that while it hasn?t been tested extensively in pregnancy, it was thought to be safe.

After the vaccine, I began to have fever and body ache for a couple of days. The next week, 04/20/2021 I began to have abdominal pain and blood in my urine. I went to the doctor. The diagnosis was that I was having a miscarriage. I was supposed to have 7 weeks of pregnancy. The embryo appeared to have about 5 weeks. It appears that after the vaccine the embryo stop developing. On 04/21/2021 the miscarriage took place without any medication taken to accelerate the process. Before my schedule second dose for the vaccine, I called the clinic and asked for a doctor appt. I wanted to talk to a doctor regarding my early pregnancy stage and the upcoming vaccine. At first I was denied. Then after a struggle I was provided with a lab test to confirm my pregnancy. On 04/12/2021 in the morning, I called the clinic to speak with a doctor and ask his/her opinion about the vaccine and my early pregnancy. After an struggle, the receptionist told me that the nurse who had the results of my pregnancy was busy. She would call me later on the date. That been pregnant or not, the vaccine was secure. I asked that I wanted to have a talk so I can make my decision. But the receptionist repeated the same. And after I said thank you but the phone was cut. That is when I decided not to miss my vaccine appt.

So my PMDD came back with a vengeance after the second dose of the vaccine. After the first dose, I had the most painful period t the most painful 12 hours of my entire life, so I was worried about THAT. Turns out I was physically fine, but mentally very unwell. It felt different/ similar to when I was 19 and tried an antidepressant that made me feel actively suicidal, so. I don't know how to describe the difference in feeling, but it came out of nowhere, was very strong, I wanted to kill myself for half of April, and it wasn't for any *reason* whatsoever, it was just hormonal. So my best guess is that the second dose interfered with the balance my birth control gives me now, and the shock to my system made it even worse than it had been in the past. This lasted from the 4th, through my period, and after, until the 19th. I was barely able to take care of myself at all during this time, and it was very difficult/ debilitating. Also scary!

I am now almost two weeks late and not pregnant. I've been having premenstrual symptoms now for the entire two weeks including sore, swollen breasts, cramping, and bloating. It's like my body is expecting my period to start any day now but it's not. Two days ago while I was brushing my teeth and getting ready for work, I suddenly got the worst sharp pains in my pelvic region and rectum to the point that I couldn't stand. I had to lay down for an hour. I've never felt anything like that before. I'm a very healthy & stress free individual that does not take any medication (birth control, over the counter meds, etc.) The Pfizer vaccine is the only "new" thing to come into my body.

My Pfizer shots were delivered on Feb 18 and March 12, 2021. I experienced irregular menstrual symptoms from March 1-March 13 of 2021. My typical menstrual cycle is 26-28 days, with 3-4 days of concentrated bleeding. My previous 3 periods were Dec 18-22. Jan 17-20, and Feb 12-16. On March 1 almost 2 weeks before my expected period, I started spotting and cramping. The light bleeding continued for 2 weeks, at which time it transitioned into my typical period with regular cramps and bleeding, in line with my usual experience. My GYN did not know what could be causing this (I later found out there have been many irregular menstrual symptoms associated with Covid-19 vaccines. I don't regret getting it, this was fairly mild, but if there is a causitive link between the vaccines and mesntrual side effects, women NEED to know this. Menstrual and female reproductive health side effects need to be observed and measured in clinical trials, and female patients need to be advised what to expect.

She was breastfeeding her 2-month-old at the time and milk supply significantly lowered so much that her child wasn't growing enough and had to switch to formula. When she had breastfed her first child, she didn't get a period for 8 months, so she definitely think that it was related to the vaccine.

I had just had my period on 02/22/21 (first day of the cycle) and then received the first dose of the vaccine the following week (on 03/04/21). I had a slight period the day after (03/05/21) which lasted about 3 days. I thought it was just a coincidence and didn't think much of it. The same issue happened after I got the second dose on 03/26/21; I got my period again. My period is usually normal (every 27-31 days), so it was definitely strange to me that my period came so soon and both times were immediately the day after the shot. It was just a normal period with no blood clots or anything abnormal, but I do feel like it's an adverse reaction of my body to the vaccine.

At the exact moment of injection , complete arm tense. After standing immediately on 1st injection I experienced dizziness. During my ?observation? 15 minutes I was walking around the store with blurry and spotty vision. I almost felt like I was going to fall over, and had the feeling immediately that I needed to go to sleep. After eating ( this was at 9 in the morning after a full night of good sleep) I felt as if I needed to go to sleep immediately. I continued to sleep for two hours after the first dose. My menstrual cycle was delayed this month as well by 7 days and very heavy. The second dose was very similar. I have to say the pharmacy was excellent as I told them my experience with the first dose. I sat for 15 mins to make sure I wasn?t going to fall. I sat but still felt dizzy and saw spots with blurry vision. Same reaction. I went to sleep without hesitation like there was not a force in the world that could stop me. I have continued on both occasions to feel the effects around 24-48 hours after.

I was 22 weeks pregnant when I received the first dose of the Pfizer vaccine. Then, 2 weeks later when I was 24 weeks pregnant, I started having vaginal bleeding. I was in the hospital for 3 days as the doctors believed I may be going into very early labor. They suspect a partial placenta abruption. As a result, my cervix was found to be short, also indicating potential early labor coming. I was put on bed rest. Two weeks after the bleeding started, I lost much of my mucus plug (at 26 weeks). When at hospital at 24 weeks, I was given steroids to make my baby?s lungs develop faster just in case he?s born soon. I was also prescribed progesterone which I?ve been taking nightly. I?m now also taking magnesium supplements and drinking chamomile tea. This may be unrelated, but I have also been found to be low in iron so now I?m taking iron supplements too. Due date is Aug 2, 2021; I?m 31 years old; I am currently 29 weeks pregnant and still have not gone into labor; This is my second pregnancy, my first pregnancy was two years prior, and it was 100% healthy.

At the beginning of January, my husband and I had already been trying to conceive. I received my second dose vaccine on 01-07-2021. In the first week of February I found out I was pregnant. By the end of February I had a miscarriage. I had the miscarriage on 02-24-2021. The day I miscarried I was going to have my first gynecological appointment to check my baby. I do not know if the vaccine had anything to do with my miscarriage. I was hesitant to getting my second dose but I still went through with it. I just think it is important for mothers who are expecting to wait at least till their second trimester to receive the Covid 19 vaccine, my opinion.

Awoken throughout the night with extreme body aches (Eye sockets, neck, hip sockets--worst )and migraine. Around 5:30am I took two extra strength Tylenol to no avail. I proceeded with chills, shakes, fever, cold hands and feet, sweating, exhaustion, and loss of appetite. These expected symptoms subsided/ were manageable at approximately 5:30 pm. At 7pm, I began having trouble climbing the stairs and had intense pain in the center of my chest. I could breath alright (I was NOT light headed), but couldn't alleviate the chest pain. I went to sleep at 8:30pm in hopes that it would dissipate. **(Did not go to hospital because we are military, my husband is TDY and I had no one to watch our children. This is not to downgrade the fear or intensity of the pain. I have a very high pain threshold- this was awful.)** Saturday (Day 3 after vaccine) no chest pain, but began spotting (my period is very regular and tracked diligently-I'm not meant to start for another 8 days), still had a very sore neck/ migraine, and swollen/painful lymph nodes in my armpit ( on the vaccine side). Sunday (day 3 after vaccine) still spotting heavily, painful lymph nodes, and migraine.

Hives started on my elbows for about 10-14 days, then spread to my knees, and feet, then spread all over my body. Originally thought it was a medication reaction and switched oral contraceptives, but hives persisted. Stopped taking all medications and supplements except for lamotrogine and antihistamines. Contacted my immunologist on March 5, 2021, "I am now weaning off of my lamotrigine so I can clear everything out of my system. In the last couple weeks I have Taken prednisone 40mg x2 days, 30mg x2days, 20mg x 2days, 10mg x 2days. Then did a medrol dose pack. And have taken hydroxazine, and Zyrtec. The oral steroids just toned it down a little. The day after I finished the medral I woke up the the worst they have ever been. The only place they weren?t was my face. I?ve been applying hydrocortisone 2.5% 2 weeks on 1 week off and it seems to help it mostly calm down during the day. At night everything flares up and in the morning I wake up to find them back. Some days better than others. I also got blood work done and everything was within normal ranges. My last allergy shot was in December." Started on 2 zyrtec and famotadine twice daily, along with hydroxazine, benadryl, or doxepin PRN. This helped for about a week, but the hives worsened after that week. Spoke with immunologist again. Started on Xolair injections. Following the second Xolair injections the hives decreased significantly. Taking the Xolair injections monthly and taking zyrtec in the morning and famotidine before bed keeps the hives mostly at bay with few appearing every few days, but not all over like they were. (I have picture documentation for all.) I have since started back on all supplements and medications with no adverse reactions that were not previously stated. Other adverse reactions are: abnormal menstrual cycles starting in January (I have been extremely regular with the same week since the start of menstruation at age 11, even after pregnancy), severe brain fog and difficulty remembering, new onset gut issues, edema and angioedema with the hives.

She spoke with NP and tried oral steroids, and multiple antihistamines with no relief. She stopped all meds and supplements. She spoke with immunologist and started on multiple antihistamines daily. She had no relief and at times worsened and started on xolair injections. Xolair was the only medication that has helped. There were still hives but not every day and not head to toe like they were. She also has to take antihistamines. When she didn't, she break out in more hives. She has taken multiple pictures to document. Since Jan2021, she was struggled with abnormal menstrual cycles, gut issues, severe brain fog, edema, angioedema, along with the hives. The adverse event result in doctor or other healthcare professional office/clinic visit. The patient received treatment for the adverse events which included mult. meds, stopped all current meds, and Xolair. Outcome of the events was not recovered.; Sender's Comments: Based on the information currently available, a possible contributory role of the suspect vaccine BNT162B2 in triggering the onset of angioedema cannot be excluded.

I went to the ER and they confirmed there was no fetus, and they did testing. It came back that I had passed the embryo. They performed some blood work, which included a test for antibodies and that came back elevated so therefore I was told to have Hashimoto's Disease. Prior to the vaccine I was not diagnosed, so this is the information that I have. The time of miscarriage, I would have been 5 weeks pregnant so it was considered an early pregnancy loss. So I have had one pregnancy three years ago and since then, I have been trying to get pregnant and through IVF. My estimated date of delivery would have been January 27, 2022.

My menstrual cycle started a day before my shot was administered. I track my cycle with an app, and it usually lasts 3-4 days for the past couple years, at least. It?s also quite regular. The cycle I started the day before I got my shot lasted an extra three days at least, and was slightly heavier flow for longer than usual. I count that as my first effect that was not a ?normal? symptom. Yesterday, 5/11/21, I started ?spotting? again, or having trace amounts of blood when I urinated. I?ve felt bloated as well the last couple days, as I do when I?m starting my cycle. Today my cycle has gone from ?spotting? to ?light? flow, with more noticeable cramps; in other words my cycle seems to be starting again, two weeks ahead of schedule. My next shot is scheduled for this upcoming Monday, 5/17/21. My next menstrual cycle was supposed to start around 5/25/21. My cycle is usually consistent within a day or two of its estimated schedule.

My period was extremely heavy for a few hours on day two of my cycle. I couldn?t leave the bathroom, the blood was very thin and had lots of clots. It was just evacuating my body so quickly. Normally, my period is very consistently light. This has never happened to me in my entire 20 years of menstruating. It was painless, no cramps, just very heavy and then after a few hours of nonstop bleeding, it went back to normal. It?s almost like the entire living decided to shed in a few hours rather than the extended few days that it normally happens in. The whole cycle still only lasted a few days like normal, just those few hours were noticeably abnormally heavy.

The day following my vaccination (4/24/21) I awoke feeling completely nauseous and dizzy. Upon getting out of bed I immediately sat on the floor due to the extreme dizziness and fear of passing out I felt. After a few minutes in this state I vomited. I had a fever which I managed with Tylenol. I felt fatigued and weak the entire day. I ran a fever the entire day, again managing it with Tylenol. The following day (4/25/2021) my fever was gone and I felt better, however about midday I began experiencing cramps and vaginal bleeding. I was 5.5weeks pregnant with an estimated due date of 12/24/2021. I went to the ER with concerns of a miscarriage. Based on abdominal ultrasound and subsequent HCGquant testing over the next week it was determined I had encountered a miscarriage and lost the baby.

her period is now 11 days late; tired; stabbing shocks in her chest (chest pain) that lasted for 3 hours; heart started to pound; she had a metallic taste in her mouth; face was numb and warm; face was numb and warm; heart rate at 160 bpm; her mouth/tongue felt itchy; her mouth/tongue felt itchy; throat felt itchy; lips numb; This is a spontaneous report from a contactable consumer (patient) from a Pfizer Sponsored Program. A 32-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection), dose 1 via an unspecified route of administration, administered in left arm on 28Jan2021 16:00 (lot number: EL3247) at the age of 32 years old, as 1ST DOSE, SINGLE for COVID-19 immunisation. Medical history included asthma from 3 years, allergies (all her life), Chiari malformation from 10 years, vocal cord dysfunction from 3 years, Vitamin D low, constipation and Ferritin low. Concomitant medications included albuterol [salbutamol] (ALBUTEROL) taken for asthma; clarithromycin (CLARITIN) taken for allergies; iron taken for ferritin low; magnesium taken for constipation; and vitamin d [vitamin d nos] (VITAMIN D) taken for Vitamin D low; all taken from an unspecified start date and ongoing. The patient reported she had the first dose of the Pfizer COVID 19 vaccine on 28Jan2021 at 16:00PM in the left arm. About 10 minutes into her wait period (28Jan2021), her heart started to pound; her lips numb and face went numb and warm; she had metallic taste in her mouth; and her mouth/tongue and throat felt itchy. She went up to the nurse to tell her about her symptoms and they hooked her up to an O2 monitor that showed her heart rate at 160 beats per minute but her 02 was okay, it was not under 97%. She was given a generic form of Zyrtec. They monitored her for an hour and her heart pounding stopped. The metallic taste was very brief, and lips and face numbness, and mouth and throat felt itchy all resolved that same day. The next day (29Jan2021), she was tired. Then about 50 hours after the shot, in the night on the 29Jan2021 to 30Jan2021 she started getting weird stabbing shocks in her chest (chest pain) that lasted 3 hours. She would wake up with the pain and then fall back to sleep. It happened several times for a few hours then went away. Lastly, she added that she never ever misses her period but now she is two weeks late (also reported as 11 days late) and she is not pregnant. She expected her period to start on 02Feb2021. She did visit her allergist before getting the vaccine and he said none of her allergies were related to any of the ingredients in the shot. Then she saw the allergist again after the shot and the allergist didn't think she needed to be concerned as the allergist said her symptoms are not in line with an anaphylactic reaction. She is planning to receive the second dose of the vaccine on 18Feb2021. Outcome of the event 'stabbing shocks in her chest (chest pain)' was recovered on 30Jan2021. Outcome of 'her period is now 11 days late' was recovered on unspecified date. Outcome of tired was recovered on 29Jan2021, while outcome of the remaining events was recovered on 28Jan2021.
