Help me, am i pregnant?

Patient: I had sex three times all three times with a condom and pulling out, I took plan b after the second time. Then this last time I had sex with a condom and pulling out again and I am within the 72 hours of plan b being effective. If I took it already will it help with this last sexual intercourse that I had? What are my chances of being pregnant using a condom and pulling out?

Doctor:
