Forgotten Pill

So this morning i was going my makeup cause my bf and i were going on a date, and my alarm went off to take my pill and i was like after my makeup ill take it, but i guess i forgot and my boyfriend and i had unprotected sex. He came in my mouth, but he leaks pre a bit, it was short which isnt like usual, we last for hours haha but just wanna know the chances of me being preg? I took my pill right after we had sex cause i rememered.
