Free text: I have had a very heavy period after not having one for 7 months (Im in early menopause) and only spotting for the 6 months prior to that. This very heavy period had bloating and cramping and came in 4 days after my 2nd shot. It was definitely a result of the shot. My friends are having a similar symptom and this symptom should perhaps be on the list and it is very frightening to hve this happen so suddenly and unexpectedly.

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".
