Ethinyl estradiol / etonogestrel
birth control
"I've been on nuvaring for almost 3 years and it has been the most convenient, with the least side effects. I've have lighter periods especially in the last yr or so. I know others say it helps with cramps as well, but my pain hasn't decreased as far as I can remember. 

My husband says he feels it when we have sex, and when we get really energetic it tends to bruise him. I do find that the week before my period I get nauseous on and off during the day but that's may have nothing to do with the nuvaring at all.

Outside of that it's been a real awesome experience for me. No serious side effects."
