birth control
"I switched to this birth control from Yaz because my periods (although controlled) were still 7-8 days long and heavy. When I switched to this pill I gained about 8 lbs, was intensely moody, and noticed my hair and skin became extremely oily. I was on it for 4 months and it only got worse. I had breakthrough bleeding the entire time. The second month I was on it I bled for 2 weeks straight. It was absolutely miserable. I know birth control affects every person differently, but this was AWFUL for me."
