I use NuvaRing as a birth control. I take it as directed, and have been for about 3 months. Before NuvaRing I always used a condom. I had sex for the first time without a condom (but on NuvaRing) the third week of my NuvaRing cycle. I took it out Friday night, it's Monday morning and I haven't gotten my period yet. You're supposed to get it 2-3 days after you take it out, (I realize it is the 3rd day) I guess I'm just worried, seeing as it was the first time using NuvaRing as our birth control.
