"since i work at an ob-gyn office, i&#039;m somewhat of a birth control connoisseur.  i was on yaz for a year before switching over to beyaz with folate.  in the entire time i&#039;ve been taking these pills, i&#039;ve only had 3 periods even though i take the placebo pills.  also, i haven&#039;t experienced a single one of the bad side effects like i&#039;ve had with other pills.  no weight gain, no tenderness, no periods, no crazy anger, and my sex drive has improved 100% since i was on nuvaring before.   i rate yaz an a plus!"
