So I have my boyfriend and handjob and sperm got ok my hands but most of went on the blanket and i wiped the rest off... around 5 minutes later or so he fingered me and we aren't sure if he had sperm on his hands bc he said he would've noticed but the only time he touched it but the bottom was to put it back into his pants .... if he fingered me after 5 minutes and even it was exposed to air and contact with the blanket which resulted in it being wiped off... could i be prego? i'm also about to start my period in about a week or less help!
