HELP!!!!!

Me and my boyfriend have sex quite often. However we do have protected sex but before that we do it without a condom for 5 mins or less we call it the 'just for fun' but without him cumming or anything. He usually cums in the condom but even though he uses a condom he pulls it out before cumming so he cums outside but I started ovulating today having 22% of pregnancy. What should I do? Oh and yestraday we had intercourse with same old 'method' and I was at a 33% risk of pregnancy. Also my period has to come on the 11th of October . Is it gna affect it? Am I pregnant?
