I ordered my doppler back when I was 8 ish weeks. I tried a few times and gave up, but today I was just laying around and decided to try it out. I'll be 11 weeks Monday, so I thought there was a chance.
After about 5 minutes, I found it! It was consistently in the 150-160s, and definitely wasn't me. So weird/awesome - even my husband thought it was cool (and he was super skeptical about me buying the doppler in the first place!). Little bugger moved around a bunch so I lost it a couple times, but was able to find it again pretty easily.
I'm excited! Definitely gives me a little relief, since my next appt at 12 weeks seems so far away
