Birth control pill and unprotected sex

Patient: Hi i have been taking the birth control pill for about 4 months now, i ve never missed a pill or taken it more than 1 and halv hours late. But last saturday I took my pill 5 hours later. normally i take it between 9-9.30pm but that day i took it 2.30 at night. after i took the pill, me and my boyfriend had unprotected sex. Can I still get pregnant?

Doctor:
