At my worst, I had a couple periods that went on for a month. The doctor just gave me Provera to stop it and restart it. Basically, she said it wasn't a true period and my lining was building up and collapsing. (but, I guess, not truly shedding itself) It was a horrible time for me. Provera made me so hormonal! (sad, angry, etc.)
I'm new to these boards, so I don't know what you have tried. I think low carb eating helps and any exercise helps... (I mean with your cycles--weight loss is a harder ball game.)
I too am a Metformin drop out
And facial hair drives me batty. I think it grows in spurts. One day, it's not too bad and the next time I look--OMG! Where's my wax strips!!!!
