Hello, I am a 18 year old college student. About 3 days ago me and my boyfriend decided to dry hump, which we I often do. I was wearing thin underwear and he was naked. But as we were doing this he ejaculated on my underwear near my vagina and continued poking then slowly stopped. After we were finished it took me about 2-3 minutes to take of my underwear but when I did I noticed his semen might have gone through my undies since it was wet. I am terrified and wanna know if I could possibly get pregnant this way??? Also we dry humped 12 days after my period and I have been feeling weird right after the night it happened. Could this mean I’m possibly pregnant? Please help
