Birth Control
"I went on this medicine for birth control. When I first started it I only got pimples the week of my period, I had really bad cramps(to the point I threw up every month), and I was really fit. 
Fast forward 6 months- my face breaks out all the time and is never clear (no matter how much I wash it), the cramps got better, and I gained 10 lbs all in my mid area. This medicine did make my boobs become fuller and my period was on time every month. 
This medicine also made me VERY moody and I cried over the smallest things almost every day. The weight gain + countless emotional breakdowns/anxiety attacks were way too overwhelming for me so I just switched to a different BC!"
