This F the perfect way to listen to your baby’s heartbeat. Now all mothers can enjoy the pleasure of listening to their baby’s heart whenever they want, in the comfort of their own home.

Many expectant mothers worry about their unborn baby during pregnancy. For these worried mothers, it can be very reassuring to buy a fetal doppler system, especially the popular Angelsounds Fetal Doppler, which comes factory direct from Global Care Market.

What is a Fetal Doppler?

A Fetal Doppler is a device used to monitor a baby’s heart rate throughout pregnancy. The device is non-invasive, which makes it a good safety choice for all pregnant mothers. The heart rate is measured by the Doppler effect, emitting and receiving ultrasonic sound waves and monitoring the shift in pitch of the sound waves. Every returning sound wave is measured as the sound of the heartbeat heard through the speakers on the Doppler.

Ideal Times to Search for a Heartbeat

An embryo’s heart begins beating around 22 days after conception, but it takes much longer for doctors and parents to be able to listen to the heart beat. Between the 9th to 12th week of pregnancy, most fetal dopplers are able to pick up the sound of the heartbeat. Some heartbeats may be hard to find, and this is perfectly normal. Just be patient and try around more areas of the belly, eventually you will hear it!
