Fetal Heart Rate at 15 weeks gestation?
Hello all,
Yes another question from the paranoid mother here. I am currently 15 weeks and a few days pregnant. I have had ultrasounds at least every two weeks from the time I found out I was preggo in week 3 lol. I have a subcoronic hemorrhage that is the main reason for all the ultrasounds. Anyhow being the fact I have seen the heart rate from 6 weeks I have known everything. My question is when is is normal for the heart rate to slow. Let me explain here. At 6 weeks when they first got the hb it was 121 then it by like week 8 it was in the 180’s. Since then it has been going down about week 10 it was in the 170’s then the next time it was checked like week 12 it was 160 -170. Now over the last three weeks it has been between 150 to 160 if the baby is active and in the 150’s it is not. (I have a fetal heart doppler this is how I know all of this). So now in Week 14 to 15 I have noticed something that worries me and I need some reassurance as the doctors really don’t say much. The last week I have noticed it dropping to the 140’s for a second or so then back to the low to mid 150’s… Is this normal or should I be concerned that something is going wrong. I had an ultrasound yesterday and they said every thing looked "ok" I hate that word cause I always feel they are hiding something lol. I know the baby is healthy cause all the measurements, measure ahead of what I actually am usually 4 to 5 days ahead. So I know he is growing well. I just want some reassurance to the sudden from the 150’s to the 140’s this week is it normal? When do their heart rates stabilize and balance out, it has seemed to be dropping over the last weeks is that normal? I appreciate all your help, and hope you all have a good day.

The bigger the baby gets the slower the heart rate. (but not by much) Your baby has been growing so the heart rate has been slowing slighty. Maybe your baby was moving when they did the ultrasound and it was 180. When I was 8 month pregnant with my first and the doctor checked the heart rate it was 180 because he was doing aerobics in there! Normal heart rate for babies by the 5th week is 155-195. If there was a problem your doctor would tell you right away!.
Congratulations!
That same thing used to freak me out too! It really isn’t anything to worry about. I was told that anything from 140 to 170 is normal and depending on if the baby is resting or active it can be anything in between. I was also told that if the baby moves away from the sensor that it can make it look like the heart rate is going down when it really isn’t.
I don’t know if that’s true or just something they told me to get me to shut up, but my kids were all born perfectly healthy.
All those heart rates are normal, my baby has always been in the 140’s, Their heart rates will be different things at different times, sleeping, awake, active it just all depends on what they are doing in there, Your doctor will not hide anything from you if something is going on they will let you know.. Congrats and good luck
Its all normal. Both my pregnancies were anywhere from 135 - 180 depending on what baby was doing, or what I had eaten.
