I started the Nuvaring last Friday, so like one week ago. Since then, I've experienced abdominal discomfort, nausea, and a big increase in discharge. I was started to be scared of pregnancy, but after reading all this I guess it could be from the ring. After reading about the mood swings, I'm starting to wonder if maybe the extreme paranoia/ups/downs over the possibility of pregnancy might be a side-effect too? Could somebody who's been on it longer post back to tell me if the time frame/side effects are about right?
