birth control
"I have been on Yasmin since I was 15.  My periods used to last 9-11 days, were heavy, and very painful.  I can remember my mom keeping me out of school due to this.  Not only was my cycle completely crazy, I had acne on my shoulders, upper back, and upper arms.  Being in high school, something like this can be traumatizing.  Anyway after almost 6 years, I have been acne free (maybe the occasional bump or 2) and 4-5 day easy periods!  I did gain weight...but who knows if it was because of the birth control...like the lady said before she gained in all the "right" places so I can't complain about that one.  I went up a whole up size! I plan on taking this until I decide to make a little one (another 4 years hopefully)."
