I should have known better than to try it to early, but yesterday morning I very quickly found the heartbeat with my Doppler at 9w. I tried again two times last night, and once this afternoon, and can't find it again, and I tried for a LONG time. Is this normal?? I know it's early to be finding it, but now that I can't again I'm freaking out. I don't go to the Dr for another 3 weeks.
