chances of pregnancy?

So the fiancé & I were making love & he ended up cumming inside of me in the missionary position & he kept stroking me after he came! I got up & pushed & semen came right out in like two lumps lol! I always push the semen out! I've pushed the semen out for months now with no problem thank GOD!!  I had my period the week before we had sex. I don't remember when my period went off but I know my period was on on the 12th I believe. We had sex sometime that next week. Even though I pushed the semen out, I didn't take a plan B or anything. I don't believe I was ovulating that soon but I am wondering what my chances are of becoming pregnant? I really can't afford to have a baby right now. Please give some answers y'all! Thanks!
