discharge after sex

had sex the day before thanksgiving, and since then i’ve been having milky white discharge. like 10 mins after the sex i peed and it was clear and watery which is normal for me immediately after sex. i showered before we had sex so i didn’t after until friday and it’s still there. is it a yeast infection? i smelled my underwear and it only had odor once and it smelled kind of sour? but i haven’t smelled anything since that. there’s no itching, just a lot of discharge. i’m on BC and not due for period for another like 17 days. i will say thought, it feels like the kind of discharge i get after i masterbate and cum. i’m on BC, we used a condom as well. and im pretty sure he pulled out.
