SAN FRANCISCO — Anecdotal evidence from women around the country has led to questions about how COVID-19 vaccines may affect women’s menstrual cycles.<\/p>\n\n\n\n
When ABC7 News reporter, Kate Larsen, posted the question on social media, it became clear that a lot of women are experiencing cycle changes, and are wondering if it’s related to the vaccine.<\/p>\n\n\n\n
Women wrote:<\/strong><\/p>\n\n\n\n “I had my 1st COVID-19 vaccine in January followed by the 2nd in February, and since then I have had hemorrhagic bleeding with clots. This month of April was the heaviest.”<\/em><\/p>\n\n\n\n “I thought I was going crazy, and even went as far as making a doctor’s appt and switching out my BC because mine is so heavy now and its been a month straight”<\/em><\/p>\n\n\n\n “I received the Moderna vaccine in January and February I didn’t get my period for 3 months they did multiple blood test, pregnancy test and ultrasounds but everything came back normal. Then finally on April 4 I got my period and it’s been super heavy for the past 22 days non-stop.”<\/em><\/p>\n\n\n\n And some women are reporting other changes: “My period has been the lightest in years for the past 2 cycles. Was beginning to wonder if I was pushed into pre-menopause. Also my PMS symptoms haven’t been as bad from what I can tell.”<\/p>\n\n\n\n
