Me and my boyfriend were fooling around on the couch, he wasn't wearing underwear nor pants, but I had my underwear and pajama pants on (I think they are cotton and so are my underwear) . he rubbed it around the clit area until he ejaculated on my pajama pants. I heard that sperm can go through clothes. I'm just afraid and want to know from a professional. Can I be pregnant? I usually get my period around the 16th but I haven't gotten any signs aI usually get cramps and discharge before.
