"i&#039;ve been taking mononessa for about 4 years now. i have never once had a bad experience or side effect from it. off of the pill, my periods were 9-11 days, came every 1-3 months, extremely heavy and with terrible cramps, to the point that i would miss class/work due to vomiting from the pain. now, my periods last 3-4 days, i only use light tampons, i have very little cramping, have not gained a pound, and i&#039;ve never had a pregnancy scare since starting it. i&#039;ve even missed a pill here and there, and i have experienced no spotting or anything abnormal. my period is like clockwork - even down to the time of day it comes. 11 stars from me!!"
