Several women say they have experienced heavier and more painful periods since receiving the COVID-19 vaccine, and several have also revealed that they had breakthrough bleeding in the middle of a cycle.
Dr. Kate Clancy, an associate professor at the University of Illinois, tweeted in February that she had already talked about people who have experienced changes in their menstruation since they had one or two vaccinations.
Her Twitter thread has caused more women to share their menstrual worries on Twitter, revealing their heavy flow, worse cramps and irregular timing, with one saying she had 16 days of blood after receiving the Johnson & Johnson shot has.

Dr. Clancy first tweeted on February 24, but her thread still found other Twitter users looking for explanations for their symptoms.
“A colleague told me she had heard from others that their periods were difficult after the growth,” she wrote.
‘I’m curious if other menstruators have noticed changes as well? I’m a week and a half out of dose 1 of Moderna, got my period maybe a day or so early, and I’m getting into my 20s again.
‘I’m on day 3 of my period and exchange extra long overnight blocks a few more times a day. “Typically for me at the moment, maybe one or two ordinary pads (though extra absorbent, always Infinity) for the whole day,” she continues.
‘Does it have to do with the way the wax response elicits a broader inflammatory response, possibly also due to the lipid nanoparticle or mRNA mechanism? Either way, I’m fascinated! Inflammation + tissue reform = extra bleeding pants! she added.
Soon, other Twitter users were chatting with their own experiences. Although several people said their periods did not change, many who took the time to comment reported differences.
Viral: dr. Kate Clancy, an associate professor at the University of Illinois, tweeted in February that she was talking about people who have experienced changes in their menstruation.
The most common changes include heavier periods and periods that begin in the middle of a cycle.
‘I got J&J on March 15, and then I started my period about two days later – more than a week early. It was heavier than normal, ‘one wrote.
“Two weeks exactly after shot number 2, my cycle started 12 days earlier and heavier than it has been for the past three years,” said another.
‘I’m three weeks away from my first Moderna shot and started my period in the middle of a BC suit. It never happened to me in the twelve years that I took the pill. I never even noticed between periods, ‘wrote another.
“My period after the first dose of Moderna came a week early and was the most painful I have ever had,” tweeted another. “After the second dose, it came almost two weeks late and my cycle had been for years, so I knew it was the vaccine, but I was scared to say it.”
“I thought I was going CRAZY,” replied another. “I got the J&J survey three days before my period started, and it’s now … 16 days of bleeding (normal period for 5 days and then light but constant bleeding for the rest).”
They too: her Twitter thread has encouraged more women to share their menstrual problems on Twitter, revealing their heavy flow, worse cramps and irregular timing
‘Me too!’ wrote another. ‘I have a IUD and have not had a period for years, but I get cramps and see today (first dose of Pfizer was yesterday). No big deal, absolutely worth it, but weird! ‘
Monica Grohne, the founder of Marea Wellness, said her company “heard from thousands of women about COViD and the vaccine that affects their periods.”
Others discussed their own experiences on Reddit, with hundreds of other commenters.
‘I had my first Pfizer vaccine on Friday, had sore breasts on Sunday and my menstruation started yesterday. It’s two weeks early. “I’re been getting started on 26-28 days since they started 25 years ago,” one wrote.
“Mine was on time, but very heavy, which is not my norm,” said another.
To further investigate, Dr. Clancy has since compiled a survey that is open to adults who have had at least one menstrual period over the course of their lives and received at least one COVID-19 vaccination shot.
Side effects: Monica Grohne, the founder of Marea Wellness, said her company had ‘heard from thousands of women about COVID and the vaccine affecting their periods’.
Meanwhile, the US Centers for Disease Control and Prevention has its own vaccine reporting system.
According to Health, experts are not sure why some women may see changes to their periods, and so far there is not enough information to know.
Infectious Diseases expert Amesh A. Adalja, MD, senior scholar at the Johns Hopkins Center for Health Safety in Maryland, suggested that any additional pain is only related to normal vaccine pain.
Others have suggested that stress may be a factor.
‘There is no biological mechanism responsible [the] disruption of the menstrual cycle after receiving the COVID-19 vaccine, ‘said Mark Turrentine, MD, professor of obstetrics and gynecology at Baylor College of Medicine in Texas.
He also said that bleeding changes did not come up as a side effect during clinical trials.
Although there are no hard data yet on periods after vaccination, a small study among 177 patients published in the journal Reproductive BioMedicine Online in January found that 25 percent of those who had the virus experienced ‘menstrual volume changes’. and 19 percent have longer than usual periods.
Statistics: Women are more likely to report worse side effects after receiving them
On Facebook, a global support group for long-term COVID sufferers with more than 22,000 female members hosts numerous discussions about a sudden lack of periods and concerns about fertility.
One poll among more than 100 members with a long COVID found that 80 percent reported that their periods had changed since they were infected with COVID.
As for the vaccine, women are more likely to report worse side effects after receiving it, but this is according to CDC data.
In February, officials looked at nearly 7,000 responses reported to the agency’s Vaccine Adverse Event Reporting System (VAERS).
They found that nearly 80 percent of the reactions were reported by women, making them four times more likely to report a side effect than men.
It was true whether they received the Pfizer BioNTech vaccine or the Moderna vaccine, and despite the fact that women are less likely to become seriously ill with COVID-19 than men.
