pregnant or not pregnant?

before anyone starts, i know i was very irresponsible and stupid, im sorry.

my period was late for three weeks when my boyfriend invited me to go over to his house. things ended up escalating quickly and one thing to another and we were both naked. he did NOT put it in, though, he only rubbed it on the outside of my vaginal opening.

today i thought i started my period but it’s very little and brownish color. there are also some blood clots. i think it might be spotting but i am not sure

i know spotting is an early sign of pregnancy.

the only thing i’m guiding myself from is that it was really late and now i have spotting.

could i be pregnant?
