I was on Nuvaring for three months. The first few days were very unpleasant. I had a lot of cramping and just felt generally lethargic and bad.
I've been extremely emotional over the time since I went on the ring. The intensity of my feelings, especially my sadness, has increased over this time. I have also felt very lethargic. I've been tired every day regardless of how much sleep I got. I have had crazy dreams every night and wake up tired. I've felt like there is a weight on me (and there is a literal weight - I've gained 10+ lbs).
I took the ring out 3 days ago and I feel like a different person. It's like a dark cloud lifted in my life.
It's a huge relief, but I am also very angry I was never informed of this side effect. I did ask my doctor about the side effects, and the only one she told me about was excess discharge.
