So I gave my BF a handjob and he came on my stomach and cleaned it up with a paper towel and about five ten minutes later fingered me for about five seconds. Is there anyway some semen from the towel may have stayed on his finger? My period hasn't come and though it was supposed to come five ish days ago I'm not too worried about that because it's always been irregular. I'm just stressed because all the symptoms for your period about to start are also early pregnancy signs. I'm terrified please help.
