Ethinyl estradiol / etonogestrel
"This is my third month using Nuva ring. I'm on the three week cycle. It's very convenient, I don't have a consistent work schedule so I never have to worry about missing the pill. HOWEVER, this thing makes me sweat SO bad at night, I keep my bedroom in the mid 60's while my side of the bed is closest to the vent and I sleep nude. I will shower the night before and wake up covered in sweat and smell terrible! And that has NEVER been the case. I've been a very competitive athlete all my life and even in my sweatiest games I never had BO. I've also noticed extreme mood swings that third week it's in. Intense vaginal irritation to say the very least and no change to my acne, it's been bad for as long as I can remember."
