I have had two miscarriages and now im pregnant and the baby is doing great. The heart rate has been 150,170,174,than 150 i think the last rate was not accurate because the baby would not stay still she really could get a reading i say he because my husband wants a boy. He was just kicking and moving like he had ate so much candy im glad i cant feel it yet. Im happy that the baby is ikay and doing great
