pls help. 911. emergency

hello friends, i am having an issue. last week on thursday (april 7) i sort of had sex at 2 am. anyway, i say sort of because his penis wouldn't go in.. and basically i was sort of raped. some parts i wanted, some parts i didnt. i come here today to ask what is the probability of me getting pregnant from pre cum without any penetration involved. i know you have a higher chance when any type of cum is deposited near your cervix, but in my case, it wasn't so do i really have anything to worry about? i've always taken an emergency contraceptive before my ovulation date but i'm still worried. can i get pregnant if pre cum was on the OUTSIDE of my vagina? what are the odds? i'm trying to keep wishful thinking. my period comes sometime next weekend, so i'm hopeful, but i need reassurance from my fellow eve community.
