Heart Tones not heard on home Doppler but picks up fast heart rate 130-190.

I am 8 weeks 1 day and the last few days I can hear my own heartbeat and the placenta tones but not the babies heart tone. The doppler picks up rate of 130-190 for a few seconds before going away. Would this be the babies heart rate even though I can’t hear it yet?

What at home dopplers do you all use that work for early pregnancy?
