When did you find a heartbeat on a Doppler?!

Question

I just got my Doppler in the mail today and of course had to try that bad boy out but I was sadly disappointed and all I heard was my heartbeat and what I'm pretty sure was my placenta when did you find the heartbeat on a home Doppler? Thanks mamas

I'm 10 weeks 4 days.

Answer

My midwife uses one that you can't hear it until 12 weeks. Maybe you got a similar one.
