What if I can't find the heartbeat ?

Fetal Doppler | Fetal Doppler Rental | Angelsounds Fetal Dop...
Finding the heartbeat can be daunting at first as your baby may be lower than you expect. Make sure you have used a generous amount of coupling gel and position the probe low down on your abdomen. If you do not hear any sound at first, move the probe slowly until you pick up the heartbeat. The fetal heart beat sounds like a galloping horse and is very fast at 120-160 beats per minute. If you still have difficulty then refer to the leaflet enclosed with your Doppler.
