I got pregnant with my first son on NuvaRing.. so it is the butt of many jokes in our house. Especially when the NuvaRing commercial comes on.
Maybe you need a lower concentration of hormones? ...Migraines are awful! I hope you can figure out what the problem is. I never experienced any bad side effects, but I did get pregnant 11 months into using it. And no, I didn't take any antibiotics, or forget to put a new one in.... the one I was using didn't fall out... I got pregnant because it didn't work. Although.... I did get one AMAZING little boy out of the whole ordeal, so I guess its okay :)
