I have been TTC for almost a full year now and was put on metformin for 9 months since I was told I have PCOS. What else is there I can be doing to help my chances to get pregnant faster? I am about 250 lbs and it is so hard to lose my belly. Also my periods are very inconsistent. I bled on and off for the past month(couple days inbetween). I'm not sure what to do...
