So I got my doppler in the mail today and have used it 3 times! I keep thinking that I'm hearing the heartbeat, because I did so at my last ultra sound, and it sounds really similar. It's probably a good 25-30 beats per 10 seconds so I'm hoping that's it! It's down right at my pubic bone in the center and tilted back kind of under the bone. Does that sound like the right place? I sure hope so! It wasn't loud enough to pick up on the FHR monitor on the doppler so I'm just guessing for now. Even if it wasn't the heart beat it made me feel oh so better! I'm pretty sure it was though!
