When can you expect to hear heart beat on doppler?

Isabel

Today was my first appointment with my doctor, I'm 9w3d, she tried to hear the baby's heartbeat with the hand held doppler but couldn't hear it, also she said that she felt my uterus might be behind my pelvis still, she asured me it was normal, when did you firts hear your babies heart on a hand device? When did your uteurs start "coming out"?
