birth control
"I had my first round put in in 2010. The first 3 years were good. I hardly ever had a period and when I did it was real light. It was great until I realized I had put on 20lbs in the first 3 years, none of my habits changed I still was active and ate decent. When I went back in to have it renewed I didn't have a period for 3 months then it came for 3 weeks with a vengeance as well as more weight gain and I can't seem to lose it no matter what I do. So needless to say I'll be having this one removed. But it does do it's job I haven't gotten pregnant."
