I gave my boyfriend a hand job towards the end of my period, and we used tissues to clean up the ejaculate and lotion of my hands and his body. I left it on a table until he left, maybe 20-30 minutes later. I then threw out the tissues. I can't remember if I washed my hands or not before I checked my underwear for blood. I think I would've because they felt kinda gross, but It might not have been too good of a wash. There was some, and I cleaned myself up with toilet paper before putting a tampon in. My period is now 3, almost 4 days late and I'm freaking out. Could I be pregnant?
