I just found out about 4 months ago that I have PCOS. I thought the treatment sounded weird, but I guess it's not because I see many of you onthe same thing. Metformin, Provera and Clomid. How many of you were actually able to have a successful pregnancy that have been on this treatment? I was pregnant last year, but I miscarried. I was also wondering if anyone knows anything about what exactly causes PCOS. My Doc says it's that I'm overweight. But one of my best friends is much more overweight than I am, has a father, brother, and aunt with diabetes, and has just had her second child. No problems. Is there something else I could be doing?
