I have a friend who had a very mild case of COVID and was later vaccinated with AZ. She reported a transient change in her menstruation (timing and heavy flows) after both. It's interesting that reports of menstrual changes after vaccination were widely dismissed initially. Now they're being acknowledged, but even though we don't know the mechanisms by which they're happening and why they happen in some people but not others, the "experts" are telling us that there's nothing to worry about. Sadly, this default behavior of dismissing anything that anyone suggests might be related to vaccination and stating with confidence that any side effects related to them are harmless (even when we don't understand those side effects) has only hurt confidence in the vaccines and the process by which they were approved, and reduced trust in the experts who are supposed to be acting with scientific and medical integrity.
