my bf and i were fooling around and he fingered me with some precum on his finger, he said he wiped only some of it on the sheets and waited abou 30 seconds before fingering me... but could i still be pregnant?? It was only precum but I'm still worried. It was one day before my period, does that increase my chances of getting pregnant? I took levonelle one less than 48 hours after this happened, but my period is now 4 days late and i have some slight lower tummy pains on the fourth day... but I was hoping that would be because of my period, but i still haven't gotten it..... Could I be pregnant from precum or is it almost impossible?? please help im really worried!! :-(
