Can pre cum travel through clothes and get me pregnant?

hello everyone, I'm 17 years old and I need help. in 7th month me and my boyfriend were dry humping with clothes? he had underwear and pants and i had underwear and pants. He is sure that he didn't cum, he thinks that he had pre-cum, and his pants were wet. i don't remember if i was wet, but i was wet from my fluids for sure. I'm scared that I could be pregnant. Since September 8th I throw up once and I think it's from bad food, but I remembered that dry humping thing happenned, since that I'm so obsessed with pregnancy and im 100% all day paranoid. I didn't have any simptoms, except that one time that I threw up.. My menstruation since that have been right on time, and they last for 6 days, but I'm so scared.. Can pre cum travel through clothes and get me pregnant? Please help, im so scared, I didn't did anything since that with my bf, i'm so scared bc i want to find a good job and finish college. thank youbut except that my stomach feels weird, idk if it's from fear
