Probability of getting pregnant?

Ladies! So my app says 3 days till ovulation and I had unprotected sex last night. Not only was it unprotected but I was on top of him while he busted and he didn’t bust inside of me, but all his cum was around my vagina, all on my clit and all that good stuff. It seemed to be everywhere in that area. Only way I could get it all cleaned up was wiping which I feel could’ve made it worse. Is the probability high that I could get pregnant? Before you say I better use protection, I’m not opposed to getting pregnant I just would like to know if my chances are high or not so much . Any insight is great.
