the other day i and my husband were dry humping.He touched his penis after he ejaculated,then wiped it off with a cloth,washed his hands thoroughly with water(he didn't use soap) and then fingered me.he didn't dry his hands after washing them with water.Are there chances for sperm to live under his finger nails?However,we do not wish to have babies so soon and i am scared i may get pregnant.I also had slight cramps recently and i am late on my period.Am i pregnant? please help.i didn't use any contraceptive.
