Ethinyl estradiol / etonogestrel
"Since I work at an OB-GYN office, I'm somewhat of a birth control connoisseur.  I was on NuvaRing for 2 years.  I didn't experience any weight gain and it gave me a regular period, my partner and I never experienced any discomfort from it, and it was definitely an improvement from the "crazy moodiness" I had on the Depo shot.  Also, I LOVED the convenience of inserting Nuvaring only once a month.  The ONLY downside was that I had absolutely no sex drive.  As in, I never even thought about sex any more. If it weren't for the 100% change in sex drive (and the fact there's no generic yet), I'd go back on Nuvaring in a heartbeat."
