I had on ultrasound on Wednesday (we are having a baby BOY!!!!) and Baby seemed pretty sleepy and not very active. But what worries me is that his heart rate was only 127 bpm. Whenever I've heard it before, it's always been between 150-160 bpm, so 127 really worries me. Do you think it was just because he was resting? The tech didn't seem worried, but... I am.
