Some women report heavier and more painful PERIODS since they received the COVID-19 vaccine

Several women claim to have experienced heavier and more painful periods since they received the COVID-19 vaccine, and several also revealed that they have had advanced bleeding halfway through a cycle after receiving the vaccine.

Dra. Kate Clancy, an associate professor at the University of Illinois, tweeted in February that she had heard of people who had experienced menstrual changes since they received one or two vaccines.

Her Twitter thread has caused more women to share her menstrual concerns on Twitter, revealing her strong flow, worsening ramps and erratic times, with one saying she spent 16 days bleeding after receiving the shot from Johnson & Johnson.

Dr. Clancy tweeted for the first time on Feb. 24, but her thread has continued to find other Twitter users looking for explanations for her symptoms.

“A colleague told me she has heard others say that the periods were very heavy after the vax,” she wrote.

I am curious to know if other menstruators have also noticed changes? I have a week and a half off of dose 1 of Moderna, I have my period maybe a day or so and I’m sprouting as if I’m in my twenties.

“I’m on the third day of menstruation and I keep changing extra long pads at night a few times a day. Typical for me right now is maybe one or two normal pads (though extra absorbent, always Infinite) throughout the day, “he continued.

‘Does this have to do with how the vax response is generating a broader inflammatory response, possibly more due to the mechanism of lipid nanoparticles or mRNA? Either way, it fascinates me! Inflammation + tissue remodeling = extra bloody pants! ‘ added.

Soon, other Twitter users participated with their own experiences. Although several have said their periods have not changed, many of those who have taken the time to comment reported differences.

The most common changes include heavier periods and those that begin in the middle of a cycle.

“I received J&J on March 15 and then I started menstruating about two days later, more than a week before. It was heavier than normal,” one wrote.

“Two weeks exactly after the number 2 shot, my cycle started 12 days earlier and was heavier than it has been for the last three years,” said another.

“I have three weeks off from my first shot of Moderna and I started the period in the middle of a BC pack. This has never happened to me in the 12 years of taking the pill. I don’t even detect between periods,” wrote a month.

“My period after the first dose of Moderna came a week earlier and it was the most painful I’ve ever had,” he tweeted again. “After the second dose, it came almost two weeks late and my cycle has been regular for years, so I knew it was the vaccine, but I was scared to say it.”

“I thought I was going CRAZY,” another replied. “I was shot J&J three days before the period started and now it’s been … 16 days of bleeding (normal 5 day period, then a light but steady bleeding for the rest).”

‘Me too!’ he wrote one more. “I have an IUD and I haven’t had a period in years, but today I have cramps and stains (the first dose of Pfizer was yesterday). It’s not a big deal, it’s worth it, but weird!

Monica Grohne, the founder of Marea Wellness, said her company “has been listening to thousands of women about COViD and the vaccine that affects their periods.”

Others have discussed their own experiences on Reddit, with hundreds of other commenters participating.

“I had my first Pfizer vaccine on Friday, I had sore breasts on Sunday and I started menstruating yesterday. It is achieved two weeks earlier. I have been regular as a watch in a 26-28 day cycle since they started 25 years ago “, wrote one.

“Mine was punctual but very heavy, which is not my norm,” said another.

To investigate further, Dr. Clancy has since created a survey open to adults who have had at least one menstrual period in their lifetime and have received at least one vaccine against COVID-19.

Meanwhile, in the United States, the Centers for Disease Prevention and Control has its own vaccine adverse event reporting system.

According to Health, experts do not know why some women may see changes in their periods and so far there is not enough data to know them.

Infectious disease expert Amesh A. Adalja, MD, a scholar at the Johns Hopkins Center for Health Security in Maryland, suggested that any additional pain could only be related to the normal pain of the vaccine.

Others suggested that stress could be a factor.

‘There is no biological mechanism to explain it [the] interruption of the menstrual cycle after receiving the COVID-19 vaccine, said Mark Turrentine, MD, a professor of obstetrics and gynecology at Baylor College of Medicine in Texas.

He also said the bleeding changes did not appear as a side effect during the clinical trials.

Although there are still no comprehensive data on post-vaccination periods, a small study of 177 patients published in the journal Reproductive BioMedicine Online in January found that 25% of those with the virus experienced “menstrual volume changes” and the 19% longer periods than usual.

On Facebook, a global support group for long-term COVID patients with more than 22,000 female members hosts numerous discussions about the sudden lack of periods and fertility concerns.

A survey of more than 100 members with long COVID found that 80% reported that their periods had changed since they became infected with COVID.

As for the vaccine, women are more likely to have worse side effects after receiving them than men, according to CDC data.

In February, officials examined about 7,000 reported reactions to the agency’s vaccine adverse event reporting system (VAERS).

They found that nearly 80% of reactions were reported by women, making them four times more likely to report a side effect than men.

This was true if they received the Pfizer-BioNTech vaccine or the Modern vaccine and, despite the fact that women are less likely to fall seriously ill with COVID-19 than men.
