"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&#039;t lose. another negative it gave me chronic headaches and an upset stomach 24/7. another plus was that i didn&#039;t get pregnant on this pill! overall great pill for acne, bad for other side effects."
