so my boyfriend and i were grinding. he was wearing boxers and i was wearing underwear and pj shorts. he is worried that pre-cum could have somehow gotten on me. he thinks that i have a chance of getting pregnant? we had no direct skin on skin genital contact. its just that he thinks the semen, and sperm, could have seeped through the fabric or gotten on my skin (my shorts were relatively short i guess). is there any chance that i could become pregnant from this? also, i should be getting my period around now, but theres not a lot of blood? maybe im spotting?
