Help...

So my boyfriend and I had unprotected sex last weekend then a few days after that JUST FOR A FEW MINUTES LIKE 2-3 MINUTES. Is there a possibility I could be pregnant. Yes we pulled out but later on read that it's pointless to do that... And my periods supposed to start tomorrow and he knew I didn't want to do anything like that until I'm on birth control and had a condom... Please no rude comments…
