Heard the heartbeat

At my first appointment we saw our baby and saw the heartbeat but didn't get to hear it.  I have a Doppler that I got with my first, so I tried using it a few days ago and didn't hear anything.  I just used it today, 10 weeks 1 day, and heard it loud and clear. 165-170 heart rate. I feel so much better now!  I know it's not good to use the Doppler often, so now I don't feel the urge until my next appointment.  For those trying to find yours at home, I found mine on my left side, right where my c section scar is (about an inch below and 3" over from my hipbone).
