What's my chance?

So this might be difficult to explain, but I'm going to try anyways. So I've been on the patch for a few months now and it's gone well, but Friday (oct. 21 ) my patch fell off, and I reapplied another patch that same day, what I was supposed to do. The patch stayed on until it fell off once again on wednesday, (oct. 26) then I had no more patches so it was NY patchless week, something happened that Friday and I had to start birth control pills, and 6 days later from starting the birth control pills I had unprotected sex that lasted only 1 minute, he didn't finish inside me, and we wiped off his precum before doing anything, what's my chance of being pregnant? Thanks in advance for taking the time to read this.
