What would you say my chances are?!?

So my man and i started getting hot and heavy and this got a little out of hand. I never let him have sex with me without a condom before but i let him try it out for a minute or so. After my senses hit me i had him put a condom on. He never even came that night at all. So no cum was inside me what so ever. When i got home i started thinking about pre cum so the next morning i bought some plan b. I also asked him if he had peed earlier that day to clear everything out and he said yes. Would you say with not cumming, peeing so no sperm were left over and plan b i should be okay? Thank you!
