OH MY GOD. Me too. I'm so sorry it's happening to you too. I also had to undergo an endometrial biopsy because my gynecologist refused to believe I sometimes have 14-day cycles. It was negative and I guess I'm glad she checked--but still. For the last five years any gynecologist I've said the word "perimenopause" acts like a) they've never heard it before and have no idea what it is, and b) it couldn't possibly be causing me as much distressing weirdness as it is. WOMEN gynecologists, mind you.
I wish you all the best. I hope menopause is everything you hope for.
