Ethinyl estradiol / etonogestrel
birth control
"My experience has been good so far. I've been on Nuvaring for three weeks  now and I'm about to have my first period. I have not gained weight, it has helped clear my acne and I am not pregnant, so it works. The only downsides have been lots of breast tenderness which has FINALLY passed and bad cramps, randomly. I've never had bad cramps so that part does suck. I plan to continue using this form of birth control."
