how likely can you be pregnant from precum?

so the day after my period ended my and my boyfriend had sex that night drunk🙃 and then again when we woke up. the weekend where i ovulated we had sex for three days he pulled out every time we had sex. i’m peeing a lot, my boobs hurt, and i’m extremely tired i can’t even hold my eyes open sometimes and feel super weird. i’m also 3 days late for my period. (i wouldn’t mind if i was, but i was just wondering)

i would just like to hear you guys’ perspective, thank you:)
