Ethinyl estradiol / etonogestrel
"I started using the NuvaRing just yesterday and I have already noticed a dramatic change in my moods. I quickly go from happy to sad, to mad. I felt like I was insane several hours after insertion. Hopefully I can get over the mood swings because other than that I believe the NuvaRing was the best choice for me. It doesn't hurt at all, it's easy to use, and my partner said he felt it during sex but not enough to distract or bother him."
