birth control
"I've been taking birth control regularly since I was 17 and this is by far my worst experience (I've been on 6 different pills that I can remember). Within the first month and a half I gained 12 pounds which has never been a problem before on any other b.c. The pills did nothing to help with the cramping that comes with a period, or with my endometriosis pain. All and all I was completely dissatisfied with this medication. The only "positive" here is that I didn't get pregnant while on this medication."
