Ethinyl estradiol / etonogestrel
"I've been using Nuvaring for about a week, switching from the pill Aviane. I've been on about 6 different types of pills since 2008 and each has made me extremely irritable with horrible mood swings. Not so much with the lower dose pills but still to a point that interfered too much with daily life. Nuvaring has the lowest estrogen for combined hormonal birth control and doesn't go through the gastrointestinal tract, and so far, it's been great. I do not feel crazy anymore. Unfortunately I have to be on birth control for ovarian cysts, so I am thankful that this is available. It's a bit pricy but I'd pay more to keep craziness at bay. I hope that it continues to work well."
