Does the COVID-19 vaccine affect your period? New study sheds light – DailyMail TV

A stress-induced period is certainly possible if you have an IUD. When you have an IUD, your ovaries are not being controlled in the way that the pill or shot controls and suppresses ovarian activity. It makes even more sense in that scenario that there could be fluctuations in hormones or ovarian function, Dr. Schwartz continues.

While you are practicing social distancing and being vigilant about handwashing and sanitizing around the house due to COVID-19, we should practice the same type of hygiene care with your period products. Boil anything made of

What About Women Who Might Be Thinking About Pregnancy Loss And Vaccination

So, it is not as alarming as one would thinkpregnancy loss is actually pretty common. Its about 20 percent of all confirmed pregnancies. So, all pregnancies that might be confirmed by a home pregnancy test, about 20 percent of them do result in a loss after that point. So, its much more common than scientists initially conceived. And there have been two studies that have come out at least showing no effect of COVID vaccination on miscarriage. The data have been pretty limited. Theyve been looking at later losses because theyve been using claims databases. Some of them actually might rely on self reported data. I dont know if youve heard of the v-safe. So, its basically when I got my vaccination I actually got invited to participate. Its like this link that was sent to me and I just filled it out based on how I was feeling, what are my symptoms. And Id get a questionnaire through my text messages, I think it was like every week after I was first vaccinated, and then it was like every month thereafter. That is a sort of national dataset of individuals who did opt in to complete the questionnaires after they were vaccinated. And that study also did not find any association between COVID vaccination and miscarriage.

What Can You Say About Results At This Time

I agree that its frightening. Theres so little thats known. We need to validate the feelings that people have, their fears about vaccination. But I can tell you that millions of people have been vaccinated and theyre doing just fine. And again, theres very little reason to think that the vaccine would be harmful to menstruation, fertility, or any of these other outcomes.

How Researchers Used Menstrual

Researchers tracked 6 consecutive months worth of menstrual-cycle data for each vaccinated and unvaccinated woman. For vaccinated women, researchers began noting details about their menstrual cycles 3 months before their COVID-19 vaccines and continued for 3 months after their jabs, including the month in which they received their shots.

Study data showed that:

  • When women received their first COVID-19 vaccines, their menstrual cycles increased temporarily by 0.71 days.
  • Those who received their second COVID-19 vaccines during the study saw their cycles temporarily increase by 0.91 days.
  • Women who received their first and second COVID-19 vaccines during the same menstrual cycle during the study experienced a temporary menstrual-cycle increase of 2 days.
  • During the same period, unvaccinated women didnt experience a change in cycle length.

While COVID-19 vaccines had a temporary effect on the length of menstrual cycles, the one-day fluctuation in cycle length did not nearly approach or exceed 8 days. Any change to menstrual-cycle length thats less than 8 days is considered normal, according to guidelines from the International Federation of Gynecology and Obstetrics.

Additionally, the vaccines did not affect the number of days that women had their menstrual periods, according to the research.

What You Need To Know

Does the Covid vaccine affect the menstrual cycle?

Increased stress, changes in weight and exercise, and other major lifestyle changes can affect menstrual cycles and all of those changes are common during the COVID-19 pandemic. Additionally, studies have shown that some women who had COVID-19 experienced changes in the duration and flow of their menstrual cycles.

Some people have reported changes in their menstruation after receiving the COVID-19 vaccine, including changes in duration, flow, and accompanying symptoms such as pain.

What Should I Do If I Notice Menstrual Cycle Changes After Getting The Covid

If your period is slightly off, don’t panic. However, you should talk to your doctor right away if you’re 1) pregnant and experiencing abnormal bleeding, 2) hemorrhaging or experiencing incredibly heavy bleeding, or 3) post-menopausal and bleeding.

“In those situations, you’d need to get in touch with your doctor immediately and always make sure they do a pregnancy test if you’re experiencing a different bleeding pattern and there’s a chance you could be pregnant,” Dr. Polaneczky says. “Other than that, if it’s something like spotting or a slightly late or a slightly early period, it can probably be watched through a cycle, and if it persists throughout the following cycle, see your doctor.”

Generally, one irregular period is not cause for alarm. “We really only tell people to let us know if happens several months in a row or its happening multiple times during a year,” Dr. Gunter says. “A one-off isnt medically concerning.”

However, there is concern that stories of early or heavy periods might prevent women from getting the vaccine.

“I think we need to be really careful how we discuss it so we don’t frighten women with a theoretical concern,” Dr. Polaneczky says. “I’m not advising women anything differently based on these anecdotes.” In other words, there’s no reason not to get the vaccine.

What Might Explain It And Who Is At Risk

So far, it remains unclear what the biological mechanisms behind these period changes might be and who might be more at risk of experiencing them.

Drs. Lee and Clancy are yet to figure out whether or not there are any factors associated with the likelihood of going through a menstrual cycle change after getting a COVID-19 vaccine. However, Dr. Clancy noted that they are considering some hypotheses.

If I were to make a guess, I would say if somebody already has a disorder that might affect bleeding and clotting or has had issues with bleeding and clotting in the past, thats a reason to at least talk to your doctor first if you havent gotten the vaccine yet, just to see if they have thoughts about whether one vaccine better than another .

Dr. Kathryn Clancy

She also noted that there is a small chance that bodies that have more endometrial practice like bodies that have had a lot more menstrual cycles, basically, so older people, people who have been pregnant, birthing people themselves theres a chance that those bodies might be slightly more likely to have heavier periods , simply because the vasculature of the uterus is going to be a lot more established in .

Dr. Scott also hypothesized that a persons unique hormone cocktail may play a role in how they experience periods after getting a vaccine.

Many of us have been stressed since the start of this pandemic and well before, Dr. Scott emphasized.

Why Has My Menstrual Flow Changed After Covid Vaccination

Some women have reported having a particularly heavy period and others an unusually light one. Emma explains that âone possible reason might be that the uterus lining itself also contains the same chemical messengers, cytokines, that regulate inflammation and if these are affected by immunisation some women might notice some changes in bleeding.â

Emma also mentions that âsome women may be taking NSAIDs like ibuprofen or aspirin to help deal with vaccine after-effects like fever or aches and pains, so these too may make a small difference in menstrual flow.â

Those taking oral contraceptives, a typically good indicator and regulator of the menstrual cycle, have also reported irregular bleeding. Emma explains âthat the most common reason for women on oral contraceptives to have breakthrough bleeding is unreliable absorption of the pill . Given that about 1% of women fall pregnant on the pill every year, this is not unusual.â

Do Covid Vaccines Affect Menstruation

How can the Covid vaccine affect your period? – BBC News

Some women say their periods change after getting vaccinatednow a BU researcher is on the hunt for a possible link

Some women across the United States have anecdotally reported that after receiving their coronavirus vaccines, they experienced heavier, earlier, and more painful periods. Now a Boston University researcher is leading one of five teams awarded a total of $1.67 million from the National Institutes of Health to investigate whether COVID-19 vaccines have an impact on menstruation.

Lauren Wise, a BU School of Public Health professor of epidemiology, will look for evidence of COVID vaccines affecting periods through Pregnancy Study Online , the NIH-funded online study she runs that follows women trying to conceive from preconception through six months after birth.

The study has been collecting data since 2013 on many aspects of female health and fertility, including regularly asking participants questions about their menstrual cycles and inviting them to use a menstrual charting app.

Wise says, using PRESTO data, she and her team will evaluate SARS-CoV-2 vaccination and changes in menstruation during six cycles of follow-up.

What Do Anecdotal Reports Say

Let’s first take a look at the menstrual changes people have said they’ve noticed, most of which appear to be short-lived.

“The most common thing people report is a heavier period than usual, and the next most common thing is a later period,” said Dr Male, who is running a study in the UK investigating whether these short-term changes could be linked to vaccination.

“Most people say that happens for one cycle some people say they have two periods out of whack.”

Dr Male said the changes did not appear to be associated with any single vaccine, and that they rarely extended beyond one or two cycles.

Similarly, researchers in the US have said the self-reported menstrual changes they’ve analysed also appear to be short-lived, but that people’s experiences were highly variable.

“, people on long-acting hormonal contraceptives, people on gender-affirming hormones and post-menopausal people were all reporting effectively surprise periods or breakthrough bleeding,” Kate Clancy, an associate professor at the University of Illinois, told The Guardian.

Healthcare worker Kaye Kingham, 38, was recently taken by surprise when she noticed changes to her menstrual cycle after getting the second dose of the Pfizer vaccine.

Her period had come a week early, which was unusual given her regular cycle.

“Exactly 28 days, give or take a day it was pretty clockwork,” said the Victorian, who kept close tabs on her cycle after switching to a different type of contraceptive pill six months ago.

Viral And Host Factors

Virus proteins

Multiple viral and host factors affect the pathogenesis of the virus. The S-protein, otherwise known as the spike protein, is the viral component that attaches to the host receptor via the ACE2 receptors. It includes two subunits: S1 and S2. S1 determines the virus-host range and cellular tropism via the receptor-binding domain. S2 mediates the membrane fusion of the virus to its potential cell host via the H1 and HR2, which are heptad repeat regions. Studies have shown that S1 domain induced IgG and IgA antibody levels at a much higher capacity. It is the focus spike proteins expression that are involved in many effective COVID-19 vaccines.

The M protein is the viral protein responsible for the transmembrane transport of nutrients. It is the cause of the bud release and the formation of the viral envelope. The N and E protein are accessory proteins that interfere with the host’s immune response.

Host factors

Human angiotensin converting enzyme 2 is the host factor that SARS-COV2 virus targets causing COVID-19. Theoretically, the usage of angiotensin receptor blockers and ACE inhibitors upregulating ACE2 expression might increase morbidity with COVID-19, though animal data suggest some potential protective effect of ARB however no clinical studies have proven susceptibility or outcomes. Until further data is available, guidelines and recommendations for hypertensive patients remain.

Transmission And Prevention Research

Modelling research has been conducted with several objectives, including predictions of the dynamics of transmission, diagnosis and prognosis of infection, estimation of the impact of interventions, or allocation of resources. Modelling studies are mostly based on compartmental models in epidemiology, estimating the number of infected people over time under given conditions. Several other types of models have been developed and used during the COVID-19 including computational fluid dynamics models to study the flow physics of COVID-19, retrofits of crowd movement models to study occupant exposure, mobility-data based models to investigate transmission, or the use of macroeconomic models to assess the economic impact of the pandemic. Further, conceptual frameworks from crisis management research have been applied to better understand the effects of COVID-19 on organizations worldwide.

Even More Menstrual Cycle Disruptions For Women With Endo Or Pcos

Can the COVID

Evidence from the study published in BMJ, which included about 1,200 women with records of their menstrual cycles and vaccination dates, showed that people with a preexisting diagnosis of endometriosis or PCOS were more likely to notice disruptions to their cycle than people without those diagnoses.

That could suggest that, in some people who are already vulnerable to cycle disruptions, the vaccines could be having an effect, says Victoria Male, PhD, one of the study authors and a lecturer in reproductive immunology in the department of metabolism, digestion, and reproduction at Imperial College London’s Chelsea and Westminster Hospital Campus in the United Kingdom.

Where Can I Learn More About Vaccines And Womens Health

I would highly encourage patients to use reputable sources to obtain further information as our knowledge around this virus evolves, Dr. Vijayakumar said. Use sources such as the CDC, NIH, and other reputable organizations to obtain accurate information. Social media rarely publishes information that undergo the rigorous scientific testing and analysis that these organizations routinely perform.

Fighting this pandemic should be everyones main concern, she said. Vaccination can prevent you from getting very sick, stop the spread of the virus, and can save lives. The short-term effects of the vaccine are just that, short term. The benefits of vaccines far outweigh any side effects you may experience. Please get the vaccine. And if you have questions or concern, please address it with your doctor.

What Were The Main Findings

Women who received one dose of a COVID-19 vaccine during a single menstrual cycle had a small increase in cycle length meaning a longer time between bleeding of just over half a day, on average, compared to unvaccinated women. Although statistically significant, natural variability in unvaccinated womens cycles meant that many of them similarly experienced these sorts of changes month to month. There was no difference in the proportion of individuals who experienced a clinically significant change in cycle length of eight days or more.

Have you read?

Those who received two vaccine doses within the same menstrual cycle experienced a slightly longer increase in cycle length, equivalent to two days although 10% of these women experienced a bigger change in cycle length of eight days or more. These changes quickly reverted back to normal during subsequent cycles, suggesting that they were only temporary.

There was no difference in the number of days women bled for, and further research is needed to determine whether COVID-19 vaccination influences characteristics such as heaviness of blood flow, or symptoms such as pain or mood changes, the researchers said.

How Often Is This Happening

Because COVID-19 vaccine clinical trials didn’t track data on menstruation, researchers have been relying on vaccine safety-monitoring systems and self-reporting.

In the UK to date, a total of 27,510 reports of “a variety of menstrual disorders” have been reported, “including heavier than usual periods, delayed periods and unexpected vaginal bleeding” following COVID-19 vaccination.

That might sound like a lot but it’s on the background of 43.4 million COVID-19 vaccine doses being administered to women.

According to the UK’s national drug regulator, the number of reports is, “low in relation to both the number of females who have received COVID-19 vaccines to date, and how common menstrual disorders generally are”.

In other words, the regulator doesn’t consider the number of “period problems” to be high , given the normal rate of menstrual disorders seen in the wider population. Nevertheless, it says it’s investigating the reports.

Leading reproductive immunologist Sarah Robertson said this wasn’t to say reports of menstrual changes post-vaccination should be dismissed or minimised.

But she said it was important to separate instances of correlation from causation .

“There will be lots of people who link together in their mind,” said Professor Robertson of the University of Adelaide.

Expectations For Further Research

Will the COVID-19 Vaccine Affect My Period?

However, in speaking with MNT, both the people with lived experiences of period changes after getting a COVID-19 vaccine and the researchers investigating this phenomenon flagged the stringent need to include menstruating people in clinical trials, record any period-related effects, and keep the public informed of any such phenomena.

I think just remembering to ask about differences in the menstrual cycle as part of standard clinical testing of vaccines might be nice, given that we expect a huge immune response, and we know that huge immune response can disrupt lots of other inflammatory pathways in people, and menstrual cycles tend to be something that people who have periods pay attention to, and notice when things get a little bit wonky , Dr. Lee told us.

Dr. Lee also expressed some disappointment that the researchers assessing the safety and effectiveness of two-dose COVID-19 vaccines appeared not to have considered assessments of their potential impact on menstrual cycles:

This is a premise that researchers and health experts ought to rethink going forward, Dr. Lee suggested.

Adrienne also told MNT that she wished she had more information about potential changes to her period before receiving the COVID-19 vaccine so that this effect did not take her by as much surprise.

I guess it would have been good to be prepared for it ahead of time and for the scientific community to take this impact seriously, as women do tend to just suffer through it, she said.
