Chance of pregnancy?

So just this last two weeks I was on the patch, but like 2 weeks ago my patch fell off on Friday and that same Friday I put on a patch like I was supposed to, then went through the next week and the patch fell off on wednesday, and then that was supposed to be my period week since I had no other patches, but then two days after that, friday, I got put on bc pills, took them exactly the same time all week, and today, exactly a week of taking the pills I had unprotected sex that lasted for only one minute, and he wiped off any precum he had, and he pulled out way before he came, chances of pregnancy?
