My DH and I had decided that we didn't want any more children and have been using withdrawal as our birth control. It's been working for us for almost 3 years now but two nights ago we were DTD and he didn't withdrawal. It was my fault because I had thought I already ovulated days before. (had fertile cm and o pains) and told him I thought it would be okay. Stupid me, I was wrong because I had terrible O pains all day today, so I'm pretty sure I ovulated today. I'm worried now that I might end up pregnant again. We got pregnant on our first try with both my other kids. What do you think the chances are? It was only one time and a couple days before O.
