The first week of using NuvaRing I had so much nausea and breast pain that I thought i was pregnant. I use the NuvaRing for 3 weeks now, I have no sex drive anymore, I make nightmares every night, and I am anxious about every small things. And since 3 days I have vaginal irritation, very painful during the sexual relation. I also gain weight even if i'm a very active person. So I will take it out to see if i come back to normal. Hopefully I will!!! (Sorry for my bad English, i found no french forum for the NuvaRing =\ )
