Home Doppler

I’m 9 wk 3 days, my Doppler came in the mail today and I was super excited to use it. Well I got it ready to go and I’m pretty sure all I’m finding is my own heartbeat 🙄 I’m getting that on each side near my hip bones and it’s not the fast galloping sound, it’s slower. (I’ve watched a few YouTube’s and I know what I’m looking for...) Has anyone else experienced this? Im a little worried! First appt is Tuesday 5/7 so at least I don’t have long to wait...
