MedDRA: Heavy menstrual bleeding, Menstruation irregular, Vaccine positive rechallenge — Feeling: Fair

Free text: My period arrived last night, 8 days early, making this a 17 day menstrual cycle. This is unprecedented for me. After my first dose, my period arrived 4 days early, marking a 21 day menstrual cycle, which is again unprecedented for me. Nothing has changed in my diet, stress, or medications over the last 2 cycles, other than receiving this vaccination. Online research reveals women in Israel reporting similar issues.

Each entry is dated by the survey it was written in (the CDC re-sent the releases with survey dates in 2025); click a date to see that survey response. The CDC cut some text off at about 250 characters: symptoms in every release, and the other two fields in releases 9-12. Those entries are marked "cut off by CDC".
