"i started taking ortho tri cyclin lo when i was 16 because i had horrible, horrible cramps and heavy bleeding. i&#039;ve been on it for 13 years now and i absolutely love it! i&#039;m 5&#039;5 and weigh 115-120 my weight sometimes it fluctuates 5 pounds or so but i never had any major weight gain taking this medicine. i went off of it a year ago for a few months... my skin got soooo mad at me!! i had awful acne on my jaw line - my doctor told me it was hormonally related. once i went back on it my skin cleared up, my cramps were gone and my period was light and lasted about 3-4 days. it&#039;s been a wonderful solution for issues encountered during my period."
