birth control
"I have been on Yaz for five years now and LOVE it.  I've had no issues and it kept the major cramps, acne, and babies away.  I started at 16 and am now 21.  I actually have to switch because I've been having breakthrough bleeding a lot, but this is the first time in five years I've had to deal with it.  Might just be from my hormones changing with getting older.  I'm very sad I'll be leaving Yaz and will be sure to return to it if this next one doesn't work. It's treated me great!"
