home Doppler sounds?

I’ve tried my home doppler once before, and I only found my own heartbeat. so I think I found the babies today, I’m 10w5d. it was about 165, but it didn’t sound like horses like everyone says? I kinda have a cheaper one so it was more like just very quick beats, not like at the doctor. that wouldn’t be the placenta or anything else right? I’m sorry it’s just confusing, but at the doctor the HR was 163 so I thought that should be it
