"The only good thing that came from Yaz was that it completely cleared up my mild acne, I mean flawless skin. However, I went from a 34 a to a 34 d in 3 months and gained 15 pounds that no matter how much I exercised I couldn't lose. Another negative it gave me chronic headaches and an upset stomach 24/7. Another plus was that I didn't get pregnant on this pill! Overall great pill for acne, bad for other side effects."
