High fetal heart rate?

I use a home Doppler, so I guess it’s not the most reliable thing, but it always seems reflect accuracy when I go to the doctors and they use theirs.

Anyway, I’m 19 weeks and my baby’s heart rate is usually between 150-160 give or take a bpm or two. When I took it now it was fluctuating between 160-170. Is that all high for 19 weeks? My last baby was in 140s by now. Same gender for both.

Just looking for others who had a baby with a higher heart rate and it was normal.

Anatomy scan is in a week from now.
