Am I pregnant?

We’ve had sex a few times now and I’m worried I’m pregnant. The first time he stuck it in with our a condom for a minute and then he took it out and finished 5 minutes later. Then he stuck it in with out a condom and sat there with it in for a while but didn’t cum inside me, before this we were using a condom the first time that has spermicidal lubricant and I took a plan b the day after. Today we had sex quite a few times still using spermicidal condoms and him cumming on me but then the last time he came in the condom. What are my chances of bring pregnant. (This all happened in the span of a week and I’m not on the pill yet.)
