Should I take it?

It says today is my highest day of chances of getting pregnant and I had sex and my of didn't come in me but we did it in the beginning then he put on a condom and he came. For the second round we did it again without a condoms in the beginning and then he put it on. However he never came in me. Condoms were not broken. Should I take a plan b in case I can get pregnant with the pre cum?
