Just double-checking

Me and my boyfriend were cuddling. We were dry humping you know for tease. He didn't have any clothes on I had on yoga pants. After we were done messing around my croch area on my yoga pants were wet. So I believe he came a little on me. Is it possible I could have conceived if the semen went through my thin layer of yoga pants? I haven't had my period, I've been craving and my boobs are sore. Sounds like a dumb question but I'm just double checking
