I have been on the ring for a few months now. And so far it has been fantastic. No weight gain. When I first went on the ring I started experiencing horrible pains in my lower abdomine, my obgyn told me I was getting ovarian cysts, which shouldn't be happening because I shouldn't be ovulatings, don't know. However, only recently did I start feeling nausea, extreme headaches, horrible mood swings. I have however read that some women have gotten pregnant while on the ring. Supposed to have gotten my period last night or this morning, and still no aunt flow......
