HELP PLS

so me and my boyfriend had sex today, we used a condom. But then I got too uncomfortable so we stopped and he took it off but then we tried again HE PUT THE SAME ONE HE HAD ON THE FIRST TIME BACK ON.... it didn’t last long. But could I be pregnant from that ? He didn’t cum at all. It was my first time and I was bleeding really bad it lightened up, and now I’m having really bad abnormal pain
