"i was switched to this from loryna (generic yaz) two months ago. i&#039;ve been on some form of bc since age 19 to control horrible cramps and prevent ovarian cysts, and i&#039;m 27 now. hoped this pill would lessen the ovarian tenderness and stop the weight gain (40 lbs in one year!) i had while on loryna. well, i&#039;m horribly gassy and have had diarrhea every day for going on three weeks now of my 2nd pack. it&#039;s clearing up my acne and sex drive is better by a smidge, but my period is a lot longer and heavier, rather than shorter and lighter like it was on loryna. cramps are much worse, too, and i feel tired all the time. the crazy appetite increase loryna gave me hasn&#039;t changed, either. calling my gyno today to see if i can switch."
