Pregnancy Info HOME

I recently had an ultrasound. They saw two sacs. She said one had no fetal stem and the others heartbeat was only 60 bpm and probably would not survive and I would miscarry. I also thought that I was 8.5 weeks pregnant but she told me that they were the size of 5.5 weeks. I have since miscarried and passed the empty sac. I'm still bleeding and I know that the healthy sac is still there. I have an u/s schedule in four days but this is really stressing me out. Has anyone ever been told that the heartbeat was this slow and what was the outcome?
