Ethinyl estradiol / etonogestrel
"I have been on Nuva Ring for over 4 years and it was the best decision I ever made after being on the pill for a few years.  It works fantastic and even if it slips out during sex, you can have it out for up to three hours and still be protected.  I never got pregnant using this method and have been having unprotected sex with my boyfriend the entire time I've been on it.  I had no negative side effects and my periods definitely lightened. There are so many mixed reviews that I wanted to say how wonderful this method was for me but reviews can't tell you anything about how your body will react to hormones.  All you need to do is try it for yourself and if it doesn't work, try something else."
