Bubs Heart Rate at 9 week ultrasound

[Rachett]

Can anyone tell me what their bubs heart was around the 9 week mark?
I have a friend who had a scan today, she's 9w2d along and bubbas heart rate was only 137bpm. She had a scan a week ago at 8w1d and the heart rate was 167bpm.
From what i understand the heart rate will peak around 9w and then will slowly start to drop, but this is a drop of over 30bpm in a week! Could this be a mistake by the ultrasound technician? or do the think the heart rate is perfectly fine?
My bubs heart rate at 8w4d was 174bpm and then at 10w4d 178bpm. Even now at almost 25 weeks it sits around 140bpm.
Appreciate all feedback, good or bad.
Thanks in advance.

Mine was 164 at 8 weeks. Is her doctor concerned? Hope all is well

It could have been a wrong reading. Hope everything is ok

I wouldn't be worried & it's unlikely to be a mistake. If the heart rate was regular, strong it's all okay. A fetal heartbeat at that gestation (as all) will fluctuate and change. Depending on movement, what the mother has or hasn't eaten etc etc.

Thanks for your replies ladies. She will have another scan next week so only time will tell I guess. Bubs is measuring well so that has got to be a good sign.
This has been a very long awaited pregnancy and I want so badly for everything to work out well for them.

At my 6 & 12 week scans with this bub it was around 125bpm. Completely normal and nothing to worry about.
ETA: then at my 20 week scan heartrate was 167bpm.

Your babys heartrate is normal. Try not to worry.
