I am 12 weeks and 2 days today and I'm using my Doppler to check on baby as usual, BUT I have never heard these bloops and thump noises on the Doppler while listening to the heart beat. I can't feel the movement yet, but is this what movement sounds like?? I was holding the wand still.. and it also seems like baby moves away and I lose the heartbeat, so I have to readjust the wand to find it again.. Does this make any sense? Someone tell me what might be happening...!
