"i&#039;ve been on trinessa for almost 3 years because my period is out of whack, it&#039;s the only thing that works. my period comes every 4th week of the month. the first week i started taking it i felt like crap. i had almost every side effect but my doctor told me to keep taking it. it helped with my migraines and cleared up my skin. the only side effects i have now are bad cramps and back aches but other than that.. love it! definitely recommend."
