"i&#039;m 26 and was on yaz for 8 months, first time taking birth control pills. i had very tender breasts and a light two-week period for the first month. it made my acne disappear and made my body hair slightly thinner/took care of a weird chin hair that i had. no noticeable weight gain or loss. i had vaginal dryness throughout, just took a little more time to get me going although no change in sex drive. experienced vaginal irritation post-pill due to soap i was using. periods never got lighter/shorter. only slightly reduced pms (cramps, bloating, etc.)"
