Do not skip any regular pregnancy check up, cannot replace doppler with any check up2. Will display reading at steady heartbeat, please test on adult heartbeat first to feel the sound and reading3.If cannot hear the fetal heartbeat not necessarily mean that anything is wrong, baby may has moved into a position that makes detection more difficult.
