birth control
"I was on Yas a few years ago and I stopped. I had no problems with it and it did clear up my acne, which was mild anyway. When I started it up again, there are two things I don't like about it: 1. normally my periods are very heavy on day two and taper off at a five, they also pushed back every month by about a week. With Yaz, my periods are much lighter to the point where I'm only spotting but then I'm spotting for almost a week and a half and even though I'm on the blanks, my period does not start now until almost the second week of my new pack. 2. My breasts are extremely tender ALL.MONTH.LONG! At first, I didn't mind because my breasts grew by almost a full cup. I can hardly hug people! I don't know if I'll continue or at least take a break."
