PreCum pregnancy?

I’ve seen a lot of people on here saying they’ve been impregnated just by precum and I was wondering if my scenario is likely to yield the same result. I haven’t tracked my Cycle until recently so I’m not sure if I was ovulating the day of but me and my boyfriend had unprotected sex (Didn’t have a usable condom that day) for about 5 mins. He didn’t cum and had peed before intercourse. I’m currently 5 days late but my cycles have previously influenced by stress by up to three weeks. I was just wondering the likelihood of me being pregnant. Thank you in advance (Only 17 btw)
