birth control
"Very convenient, especially if your schedule makes it difficult to take a pill at the same time every day.  However, I found that NuvaRing changed the nature and odor of my discharge, which I was not comfortable.  I love the low dose hormones that it administers, but I ultimately switched to an oral contraceptive because I didn't like the changes it caused in my discharge.  It also seemed to make me more likely to develop a yeast infection.  Once I went off the ring, all those side effects stopped.    Also I had breakthrough spotting the ENTIRE first month I was on the ring."
