Join host Dr. Natalie Crawford as she talks about the latest research on both the COVID Vaccine and a COVID infection on your period. Your period is a reflection of your reproductive health, and intense immune responses or infections can certainly be stressful to the body and alter our normal hormone function. Current DATA: 19% of people after a COVID infection have a cycle change in length. People who received the vaccine had on average a cycle length of 1 day longer than prior to vaccination. If you received both vaccines in one cycle, 10.6% of people had a clinically significant cycle change of 8 days or more as compared to the baseline rate of 4.3% in the unvaccinated. In those receiving the vaccine, your period returned to normal after 1-2 cycles. TLDR - your chance of having a period change is more from a COVID infection vs vaccination, and if you have period changes for more than 1-2 cycles after a vaccine please see your doctor to investigate other etiologies of amenorrhea.
