birth control
"I was on the NuvaRing for almost 3 years and had mostly great experiences with it. I had little to no spotting, and the initial three month break-in time frame was easy and I had no irregularities.  I only suffered from one issue with NuvaRing and it was a side effect I didn't realize I was suffering from until I stopped using it for the past month (I switched to Mirena).  Over the course of the almost 3 years that I was on NuvaRing, my temper started getting worse and worse.  It wasn't anything obvious, but now that I'm on Mirena I see that NuvaRing was contributing to a fair bit of moodiness (but still nowhere near the moodiness I had when on oral birth control). I would definitely recommend the NuvaRing."
