The TransVaginal u/s revealed the heart rate at 56 bpm, they seemed discouraged. I heard it should be around 100. I am worried that this will end in m/c. I had a m/c over 3 years ago, but in 2008 had a healthy girl. Is the heart rate just so low because it is so early, or should I be even more worried? I want this baby so badly, Could someone please help me?
