Hi.. I just asked a question recently about getting pregnant through underwear to underwear genital contact, and was told it was impossible. Well, now my boyfriend and I dry humped yesterday.. Me in sweatpants and no underwear.. Him in sweatpants and underwear. Because I was wearing no underwear, could I be pregnant from this? My period is due any day now, but just yesterday I was throwing up due to illness so I don't know if it will come which is scaring me.
