Ethinyl estradiol / etonogestrel
"Nuva Ring has had both negative and positive effects on me. First of all I actually LOST weight. I have an increased sex drive and have had no slipping and it has never fallen out. Unfortunately I have had more depressive periods and cramps have been horrible. But on the most important note I have been using it for a year and haven't gotten pregnant. So it's done its job and the side effects haven't been unbearable. So if you are deciding whether or not to use this, the best advice I can give is do what is best for you and your body."
