Does COVID-19 Vaccine affect Women's Periods ?

One of the first studies to look into how the Covid-19 vaccine would influence women's periods discovered a slight but noticeable difference. According to a study released on Wednesday, over 4,000 US women were followed for six menstrual cycles and found that the next period after a shot began approximately a day later than typical. However, the number of days of monthly bleeding did not change following Covid-19 vaccination. 

"This is really reassuring," said Dr. Alison Edelman of Oregon health & Science University, who led the study and believes it is critical to inform women about their options. Following their shots, some women have reported irregular periods or other menstrual abnormalities. The National Institutes of health is financing research to see if there is a link between the two. 

The data was reviewed by Edelman's team from Natural Cycles, a birth control app that was approved by the Food and Drug Administration to help women track their menstrual cycles and predict when they're most likely to have a child. Menstrual cycles are measured from one period's beginning day to the next's first day. Month-to-month fluctuations are typical, and stress, food, and even exercise can cause transitory alterations.

Women in the research had "the most normal of normal" cycle lengths, ranging from 24 to 38 days, according to Edelman. The researchers matched vaccinated women to unvaccinated women for three cycles before the vaccinations and three cycles afterward, including the months they got a dosage. women were prompted to submit immunisation information via the app. A sample of 358 women who received both vaccine doses during the same menstrual cycle experienced a two-day increase in the length of their next cycle.
