Fetal Heart Rate at 5 weeks 6 days

by Daisee2406, Oct 22, 2008 12:55PM
What is the normal heart rate for 5 week 6 day fetus? During our first ultrasound, the heart rate was 97 bpm, is that too low?

I also thought that I was a little further along, maybe 6 1/2 weeks? The doctor seemed concerned.

Hi!
We see a low heart beat like that ALL THE TIME on the very early pregnancies.
Doctors and ultrasound techs often are concerned because we are only very recently beginning to realize that this is a normal heart rate for an extremely early gestation.

Only a few years ago we couldn't see babies that small, so the knowledge is lagging the technology a bit.  

If the pregnancy is healthy, (and I bet it is!)  the average fetal heart rate will come way up into the 160-180 range within a week or two, and then go back down to around 140.

Best Wishes!
Dr B
