bleeding. 9weeks

i need opinions while im waiting for my on call doctor to call me back. me and my fiance had sex last night and after I started heavily bleeding. it slowed down some but basically all night ive been bleeding and crying and freaking out something has happened to my baby. im not cramping or in any pain and i know bleeding after sex can happen but i never thought it would be this much. I'm 9.6 weeks and im terrified. has this ever happened to anyone else
