I'm almost 23 weeks along and have trouble finding my baby's heartbeat sometimes, too! I just got the same exact doppler as you and love it! I hear her moving around constantly and I know she's ok, but I've only been able to find the heartbeat a couple times since I just got the doppler yesterday. It is nerve wracking, but you'll find it soon! I panick sometimes too, but give up for awhile and go back to it later
