Baby heart rates

Hi everyone,

I didn't see a thread for this, but I was wondering what your baby's heart rates were at your ultrasound.

I was just checked, and my due date was pushed up by 2 days, so I was 7 weeks yesterday. She measured the heart beat at 129, which she said is on the lower end of the healthy range, which she said is anything over 120. I'm very nervous that were on the low end. 

 Can you share your results?

  • How far along are you? The HR I had at 6w isn’t a valid comparison to one taken at any other gestational date

    Come fetalhood, the HR should be 120-180 bbm, and yes, it will vary by quite a bit depending on the time you take it as there are accels and decals just like adults.

    Before 6w3d, anything above 100 bbm is good. After that, they say above 110bbm via ultrasound

  • @cmbt2 I'm 7 weeks and 1 day today. But at the time of the ultrasound I was 7 weeks.

    Considering the majority of us that had scans were done before 7w, our HRs are not a valid comparison. You can check the ultrasound thread to see if anyone had one in the last few days at that gestational age.

    you do need to step away from google. You are above the 110bpm guideline for HR. The 120-180 bpm range is for fetal HR, and you are not at that point yet.

  • My Doctor said the same thing as @cmbt2, anything over 110bpm at 7 weeks is great!  I was 7weeks 1day when I had my last ultrasound and it was around 140bpm.  Being on the low end of healthy is still healthy!  :)
