Ethinyl estradiol / levonorgestrel
"I went on this because I really liked the sound of only 4 periods a year (mine are miserable & heavy). I didn't have any spotting on the 1st pack. However, on just about every pack since then I've had anywhere from 1-3  weeks of spotting. Sometimes it's just brown discharge, other times it warrants a tampon. My periods are just as heavy and miserable. I also initially had a massive acne flare up when I started Camrese. About twice per pack I'll break out badly on my face - once during my period and about 2-3 weeks after that. I'll be asking for a different brand at my next visit. Been on this for 1 year but hey, I didn't get pregnant."
