Hi! I was on the NuvaRing some time ago for a couple of months. I was one of the unfortunate ones that it causes bacterial vaginosis. My doctor told me that my body would either be okay with a foreign object in there or it would not. And it was very unfortunate in my opinion. Aside from that, I LOVED the NuvaRing. It doesn't cause any decreased libido, like many of the pills do. As a matter of fact, it greatly increased in my case! My husband did not feel a thing when we were together. He only knew it was there because I told him. I did have a little heavier cramps, but not bad enough to make me want to change. Had it not been for the bv, I would have stuck to this birth control like glue! I thought it was great. Also, I didn't have any increased breast tenderness, nausea, headaches or breakouts of acne. As an added note - I have always been prone to getting bv. Good Luck!! :)
