bleeding during intercourse

sorry forgetting into detail ive never been pregnant before and my OBG office doesnt open till after new years.....so i just had sex in the shower so you must know its a standing up position. im only 7 weeks pregnant, and i got out the shower and when i went to wipe my private clean/dry with a toilet paper, i had a little bit of blood in the vaginal mucus....it wasnt to worrying it was just a spotting inside it but it stopped after i cleaned myself....should i be worried? is it a misscarrage or just a normal thing that happens w pregnant women when they have sex
