Ethinyl estradiol / norgestimate
"I'm in the middle of my third month using trinessa.  I'm 17 and it's the first form of birth controll pills I've tried.  Overall these first few months have been a positive experience. I had minor acne which is all gone and I never break out.  My periods are much lighter.  I only have to use a "regular" size tampon for 4 days but then I will usually spot for 3-4 more days, in which I'll just use a panty liner.  My first week and month on trinessa was pretty difficult, it messed with my vision and definitely my mood.  I became very depressed and even suicidal at times but things have gotten better since then.  I have not gained or lost any weight on the pill and still have the same appetite.  Also, It has been a great contraceptive.  :)"
