Release 7 — days 1–6 daily, dose 2
Systemic reaction (other): My period started today, six days early. Not sure if its related but thought Id mention just in case.
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".
