I gave my boyfriend a blowjob while I was on my period(I had my pants on the entire time). then I got sperm on my hand and wiped it onto the blanket. we layed there for about 10 minutes and then he drove me home(about a 5 minute drive). my hands were dry by the time I got home. I then washed my hands with soap and water, took my tampon out, urinated, and wiped with a wet rag, careful not to touch my vagina. could I have gotten pregnant?
