I just started on NuvaRing YESTERDAY and already I'm getting headaches and experiencing vaginal pain and abdominal cramping. I was on the pill two years ago for a year to regulate my periods, and I experienced ridiculous mood swings and severe depression. My gyno recommended this because of the lower doses of hormones. With the exception of 1 review, everything I've found so far has been extremely negative regarding this birth control. I'm thinking this probably isn't going to be the right one for me...
