Does anyone else feel absolutely shattered the day their period stops? I get PMT before hand, quite heavy bleeding (or at least heavier than it used to be- I don't know what constitutes heavy to a medic) but not too severe pain, but the day the bleeding stops I am wiped out. Any ideas what might be the cause? i have had tests for underactive thyroid and anaemia but both clear. I had an ovary removed 6 years ago so don't knoew if that's relevent. Just wondered if it's me or if it happens to others.
