What is the probability of facing pregnancy during risky intercourse without an anti-contraceptive pill?

Hello. I have a question about the pill the day after and the likelihood of unwanted pregnancy. I have been taking birth control pills for over a year now. I missed one tablet in the first week in the new blister and took it immediately after I checked the blister (I'm not sure if it was more than 12 hours since the omission, but I took the pills and 2 more also correctly and according to hours), on the night of Saturday to sunday I had intercourse (at the beginning it was with protection in the form of a condom, then without it, but the final ejaculation took place outside the vaa, I'm not sure if there was a preejaculate). Today, Monday evening, I took the pill the day after Escapelle. I'm very afraid of whether I'm pregnant. How likely is pregnancy?
