Hi, My Bf And I Dry Humping Last Sep 7.

Hi, My bf and i dry humping last sep 7. My period was on sep1-5. My ovulation cycle is 28-30 and my period is due 2 days from now. I get symptoms like mild cramping and sore boobs which i also experience with pms but i'm still scared i might be pregnant. I read a lot of articles that says pre cum contain sperm and it can travel through clothes is true? I wore thin underwear and he wore none but theres no ejaculation. Can i get pregnant by that? I was really stress to the point that i csnt sleep at night. I dont experience frequent urination and morning sickness though.
