I've been on NuvaRing for 4 months. In those 4 months my mood has disintegrated. The mood swings weren’t that bad the first month, but my mental state has deteriorated to horrible crying spells, headaches and horrible mood swings. It got to the point where I thought I was manic depressive. I started crying for no reason at work. I didn’t realize it was the ring until I searched for side effects. I had no idea all these problems were a result of the birth control. I thought I was going insane. I stopped taking it immediately and am looking forward to going back on the pill and for the side effects to dissipate.
