IM REALLY worried and could truly use the help. i got a 6 week ultrasound 1 week ago and the babys heart rate was 108 BPM and then went back a week later (Today) where the heart beat dropped to 100 BPM. the doctor said this is not a good sign as she wanted the heart rate tO Pick up this week and not only did it not pick up , but it decreased. does anyone have any advice or experience with this ??
