I was told that I have PCOS a week ago. I was wondering what
side effects you have had from these drugs. Over the past year, I have gained 50 pounds by changing nothing at all. This gain happened while I was doing 1.5 hr cardio a day with weights & eating around 800 calories. (5'4, 160 now). My Dr. told me that Metformin would help with lowering my weight.Yet, I'm now on Yaz. Yaz has been said to cause weight gain in some girls (maybe just from the horrible intense cravings).
