"positives: i&#039;m not pregnant, and it really has cleared up my acne. my periods are shorter, not necessarily lighter.
negatives: i&#039;ve been taking trinessa for about a year and my periods still do not come at the same time every month. i will be the first to admit i do not take it at the exact time every day, but definitely within a window of a few hours. before my period, i notice that i will get very dizzy and lightheaded, which never happened to  me before. it has also made me very emotional- i&#039;m a pretty sensitive person, but it was never this bad. finally, i have noticed that the pill reduces my appetite, however, if i do not constantly have a small amount of food in my stomach, i feel nauseous (i never vomit), it goes away once i eat."
