am i pregnant??

okay. so this has been stressing me out like crazy recently. i need some advice from my fellow women.

my boyfriend and i haven’t had sex yet but we’ve played around quite a lot. i’m still a virgin too. but last weekend we came pretty close to doing it.

here’s what happened: i sucked his dick and then he rubbed it on my lady parts and put the tip in but he didn’t come. i’m super worried that somehow there was leftover seamen on his dick that might have got into my vagina?? help please... i don’t know what to do
