My boyfriend and I had sex last week, first with a condom, then we took the condom off. He didn't go inside me, even though, I know it doesn't really matter if they pull out or not. I've been on NuvaRing for about 3 months now. It's been fine for me in the past, when I've had sex without a condom. I then went on Implanon for a couple years before going back to NuvaRing. I just worry a lot. What're the chances that I got pregnant from having sex last week? Any help for my stress and worrying is greatly appreciated!! I ask myself why I have reliable birth control at all, if I still worry as much as if I didn't have it?
