i am about 6 weeks pregnant, and i went for an ultrasound on November 2,2010 and they said they could not see the heart beating. The doctor informed me that i could have just been early or it would be a miscarrage. I have to wait and go back next friday, and i can't get it off my mind. I haven't had any symptoms of a miscarrage, but i am worried. I read online that they should be able to see the heart beat at 5 weeks.... so dose that mean its most likely a miscarrage since there was no heart beat?
