"i took yaz for 2 months for acne and it worked really good for that. i loved how i didn&#039;t have anymore acne problems. i did gain about 6lbs. and went up in bra size big time. everyone started calling me &quot;dolly&quot; seriously that was all i could see on myself! it was very painful and my breasts felt like they were going to pop! i quit taking it and they went back down to normal!"
