Ethinyl estradiol / etonogestrel
"I've been on it for more than 3 months. It's been really great; and is great for "first time" birth control because it's easy to use and a very low dose - less than 1/3rd of a normal pill dosage. While on Nuvaring, I've experienced:
Effectiveness, no pregnancies - even when used with any type of lubricant. Able to use continuously to skip periods (which I love). Larger breasts (went from a C to a full D)
Light break-through bleeding, typically for one day when I change the Nuvaring. Cramping, which can be very painful. Personally I think it's linked to constipation, which can last a few days. Taking a cheap OTC laxative helps relieve both constipation and cramps. Small weight gain, mainly in breasts and hips. My waist is the same size."
