Reports first came in from women, on social media, from various countries including the USA. I’ll share examples from Israel, as they were ahead of the rest of the world in terms of vaccinating first. Why did women reveal this on social media? Maybe their doctor gaslighted them.
Some vaccinated Israeli women report irregular menstrual cycles, bleeding
Several Israeli women who received the coronavirus vaccine have posted on social media in recent days that they had been experiencing irregular menstrual cycles and abnormal vaginal bleeding.
Haaretz, February 2021
The Health Ministry received similar reports from 13 women saying their period came early, while others reported irregular bleeding between their menstrual periods.”

No COVID trials tracked menstruation cycle changes. Trial participants were screened – women participating could not be sexually active during the trials (although a couple hundred women were not ‘compliant’ and did become sexually active, and pregnant, anyway.
Of the 270 pregnancies that occurred in women during the study despite the study’s rules about not being sexually active, ~230 of those participants’ records were lost. Of the 36 women who we have records for, 28 of the babies died. Pfizer conclusion: “No new significant safety information was identified . . .”

Pregnancy cases: 274 cases including:
270 mother cases and 4 foetus/baby cases representing 270 unique pregnancies (the 4 foetus/baby cases were linked to 3 mother cases; 1 mother case involved twins).
Pregnancy outcomes for the 270 pregnancies were reported as spontaneous abortion (23), outcome pending (5), premature birth with neonatal death, spontaneous abortion with intrauterine death (2 each), spontaneous abortion with neonatal death, and normal outcome (1 each). No outcome was provided for 238 pregnancies (note that 2 different outcomes were reported for each twin, and both were counted).

28 dead babies out of 36…that’s significant.
Back to menstruation…The media parroted what some “experts” said, and ignored what was happening, adding to the gaslighting.
‘No data’ linking Covid vaccines to menstrual changes, US experts say, published by The Guardian April 2021.
No, We Don’t Know if Vaccines Change Your Period published by the New York Times April 2021.
Vaccines not linked to menstrual changes; COVID, flu shots can go together – published by Reuters November 2021.
NIH published a study in April 2022.
Association Between Menstrual Cycle Length and Coronavirus Disease 2019 (COVID-19) Vaccination in Obstetrics & Gynecology journal:
“We included 3,959 individuals (vaccinated 2,403; unvaccinated 1,556). Most of the vaccinated cohort received the Pfizer-BioNTech vaccine (55%) (Moderna 35%, Johnson & Johnson/Janssen 7%). Overall, COVID-19 vaccine was associated with a less than 1-day change in cycle length for both vaccine-dose cycles compared with prevaccine cycles (first dose 0.71 day-increase, 98.75% CI 0.47–0.94; second dose 0.91, 98.75% CI 0.63–1.19); unvaccinated individuals saw no significant change compared with three baseline cycles (cycle four 0.07, 98.75% CI −0.22 to 0.35; cycle five 0.12, 98.75% CI −0.15 to 0.39). In adjusted models, the difference in change in cycle length between the vaccinated and unvaccinated cohorts was less than 1 day for both doses (difference in change: first dose 0.64 days, 98.75% CI 0.27–1.01; second dose 0.79 days, 98.75% CI 0.40–1.18).
The increase in cycle length for both the first and second vaccine cycles appears to be driven largely by the 358 individuals who received both vaccine doses within a single cycle (cycle four). This subgroup experienced a 2-day unadjusted mean cycle length increase (Table 3, 2.38 days, 98.75% CI 1.52–3.24), and 10.6% had an increase in cycle length of 8 days or more compared with 4.3% in the unvaccinated cohort (P<.001).”
“Our results cannot be explained by generalized pandemic stress because our unvaccinated control group saw no changes over a similar time period.”
An independent doctor surveyed more than 35,000 women, offering the most comprehensive assessment so far of menstrual changes experienced by pre- and post-menopausal individuals in the first two weeks after receiving the COVID-19 vaccine:
Investigating trends in those who experience menstrual bleeding changes after SARS-CoV-2 vaccination in Science Advances journal.
In this sample, 42% of people with regular menstrual cycles bled more heavily than usual while 44% reported no change after being vaccinated.
Among non-menstruating, premenopausal respondents (N-1,815) on hormonal treatments, a majority (65.7%) experienced breakthrough bleeding after a vaccine…
Among post-menopausal people who were not on any hormonal treatments (N-238) breakthrough bleeding was reported by 66.0% of respondents.
The post-menopausal women had no cycle for at least 1 year prior….they started bleeding again.
Unexpected breakthrough bleeding is one of the early signs of some cancers in post-menopausal people and in those who use gender-affirming hormones, so experiencing it can make people worry and require expensive and invasive cancer-screening procedures.
While the uptick in menstrual flow for some people may be transitory and quickly resolve, unexpected changes in menstruation can still cause concern.
