this is a dumb question....

and ik it’s not likely but can i get pregnant if my bf & i are making out in our underwear and he cums while he’s on top? so when we’re making out we’re basically having sex but with our underwear on and when he does cum he’s in between my legs and it’s on my underwear right where my vagina is and sometimes the underwear doesn’t go inside but it gets pushed into me if that makes sense. ik it’s not likely for me to get pregnant but my period is a bit late and i’m just panicking (which doesn’t help bc it could make it more late).
