Okay so me and my fiancé had sex today and he came on my stomach...so when he went to grab something to clean it up he had this really scared look on his face...so I asked him what was wrong and he said nothing but I need to hurry and clean it up... so I didn't think nothing of it...but know I have really bad cramps!! And my period just ended a week ago... Like I don't know if I'm just paranoid or if I am but could I be pregnant?!?!!? Please help!!!!!
