refractory period

I don't want to have sex for religious reasons.... I think.

asks:
For the past few months my period hasn't been normal. I'll go weeks or sometimes a whole month without it. I am currently in a relatively new relationship (about 2 months now) and we've had sex a few times, but he pulls out right before. I know about the risk of pre-ejaculate and such, but how possible is it to get pregnant from it?...
