Since I've been diagnosed with PCOS, I've been on birth control because I was having about 2 periods a year. I was told that weight loss possibly would improve my condition. In the past few months I've been losing weight and I am currently at a 15 lb. reduction from what I had been. I've also been excersizing. Last month and this month I've had spotting for a couple days in the 2nd week of my pills and not feeling so great, and it's not because I missed pills or anything. Could I be getting my period back? My mom thinks that it's a release of estrogen because estrogen is stored in fat and so it's throwing my body off its system. What to you all think? Sorry if there was TMI.
