Hi, V. ~
I am currently using NuvaRing and it is working well for me. Until reading the previous responses, I hadn't heard that NuvaRing could cause depression. If I had, I might not have tried it, because I'm bipolar and have a history of severe depression. But I've been on NuvaRing for almost 6 months now and haven't had any mood changes I can reliably attribute to the birth control. I chose NuvaRing after my daughter's birth because I have trouble taking the pills faithfully and got pregnant while on it last time. (No complaints, mind you - I ADORE my baby girl!) I don't use an IUD because if it fails and I get pregnant, my baby could die or suffer serious birth defects. I hope this helps.
