Try not to worry about it I know it is hard but I think you are going to be OK! I've never heard of having sex hurting a pregnancy except where there was already something wrong. If it does, the cervix was not closed entirely (a problem) and caused an infection that shows up many weeks later. If having sex caused you a problem, my bet, you wouldn't know it right then. When I was about as far along as you are with my DS the Doctor did a pap smear (freaked me out #-o ) and you know that is pulling a chunck of your cervix out and that is the most important member of the pregnancy!!! He said I might bleed some the next day which I did and everything turned out fine. If the cervix can withstand a pap smear while pregnant (which my Doctor said is standard practice) then it can withstand alittle nudging with something padded I wouldn't worry too much. Good luck tomorrow which I am SURE you will have.
