Prego??

I’m a virgin BUT my bf has rubbed his dick on my vagina. He did not cum or go inside me. Could pre cum have slipped into me?? I’m nervous and idk if this is possible. I got my period after it happened but I’m still worried something’s wrong. I’ve been having heart burn and I keep peeing/shitting (TMI lol) cause of how nervous I am. Someone reassure meee:(

Ppl keep saying “don’t have sex if u don’t know how it works” IM NOT nor do I plan to. All I wanna know is if pre cum could have slipped in if the dick was by the vagina hole.
