Okayy. So my boyfriend and I had unprotected sex last night, but he pulled and ejaculated like two minutes later. Than this morning, we had unprotected sex again and the same thing happened. And my period started either last night, or this morning, I'm not sure. But I'm extremely worried that I might be pregnant. My breasts aren't sore or anything. I normally don't get cramps, and I'm starting to get them. What do you think the chances of my getting pregnant are?
