"i&#039;ve been on ortho tri-cyclen for four months. my period use to be random and i would bleed heavily for 7 to 8 days. i had horrible cramps and nausea. horrible moody pms.  now... light periods, 3 to 4 days. same time. i&#039;ve gained weight while on the pill, my breasts got bigger but i was petite to begin with. no acne. at the beginning i was emotional for the first month but now i&#039;m not. only thing that is happening now is i have pain during sex. i would be ready to go but once my boyfriend and i try it hurts for him to put it in, and i&#039;ll have to stop because it hurts so bad. i&#039;m making an appointment now to see the doctor but i&#039;ve heard it&#039;s because of the low dose of estrogen."
