"i&#039;ve been on various equivalent brands of this birth control for just over a year now &amp; i have hardly had any side effects. the main reason i started taking it was mainly just to prevent pregnancy, but also to curb my strong pms mood swings. before taking birth control, i was very unpleasant to be around during my period. since i started taking the pill, i no longer walk around pissed at everyone &amp; i&#039;m still not pregnant. once i began taking the meds, my breasts grew about a half cup size &amp; i became very horny for the 1st month. but since that first month &amp; then an increase in dosage due to breakthrough bleeding, i have had some trouble orgasming during sex, but not enough for me to be annoyed. overall, a very good brand!"
