Scientists analyzed 23,754 menstrual cycles to find that menstruation can temporarily, harmlessly change by taking two mRNA vaccines during the same cycle.
People have been discussing anecdotes about COVID vaccines and their period for a long time.

On Twitter, users regularly voice their opinions about a link between the vaccine and their menstrual cycle.
According to the Open Access Government, Dr. Laura Payne, director of McLean Hospital and not involved with this study, said: “In many areas of health research, we don’t often study the menstrual cycle. We don’t acknowledge the potential role that hormonal changes reproductive-age women go through could have on outcomes,” she said.
A new study focuses on figuring out some truths about vaccination and menstruation, using menstrual cycle data generated by 3,959 individuals.
“Self reports are useful for rapidly identifying potential signals or rare adverse events, but they are limited by significant confounding and reporting biases,” said the authors.

The study, published in Obstetrics and Gynecology finds that participants who had a cycle length can change by only 1 day. This apparently happens only to those who are vaccinated with two mRNA doses such as Pfizer or Moderna, within one of their cycles.
But, don’t worry ladies, according to the study, vaccines won’t permanently change your menstrual cycle, however you will experience a possible change in menstrual delay of one day.
However, if you’re seeing abnormal change in your menstrual cycle, please seek advice from your doctor!
