So these are my results based on all of my ultrasounds thus far with this pregnancy:
6w6d baby measuring 6w4d and HR 105 bpm
7w6d measuring 7w3d HR between 120-130 bpm (doctor didn't give me exact number)
9w1d baby measuring 9w with a HR of 132 bpm.
I am doing a lot of reading and these numbers seem low. Should I be concerned?
