K.O.
I know that you should be able to hear the heart beat around 8 weeks for sure if not before. I would ask to have a sonogram to see for myself. The reason I say this is because my mom had this happen to her at 12 weeks in her pregnancy. She started bleeding and went to Dr. They said that she could have a D/C or just go home. My mom opted for just going home more for the natural thing too. She never went back to the Dr to see if everything was ok. A month later she started bleeding horrible. Within a few few minutes she was unconscience and they had to give her lots of blood. What they found out was that she never miscarried the baby and the dead fetus was poisoning her body. They had to do a D/C to remove the baby and save my mom. I know this seems extreem but I would hate for this to happen to someone else.
