I've struggled with PCOS for a long time, very severe sometimes with no periods for years at a time, I'm 32 with a son (how I ever got pregnant with him is beyond me and doctors!), now I would like a sibling, I'm currently taking metformin twice daily, and now I'm on a provera/clomid combination also. Just wondering how people got on with it, I'm in my second cycle, but noticed the periods are maybe 4 days, day 1 is brown, the day 2/3 is blood but quite light and day 4 back to the brown. Did it work for you ?
