How can I check my baby’s heartbeat at home without a Doppler?

A stethoscope isn’t the only way to detect a fetal heartbeat at home. Other devices might work, too, but be wary of claims. A fetoscope looks like a stethoscope combined with a horn. It’s used to monitor fetal heart rate, but it can also detect a heartbeat as early as the 20th week.

What does a Doppler ultrasound involve?

A Doppler ultrasound is a test that uses high-frequency sound waves to measure the amount of blood flow through your arteries and veins, usually those that supply blood to your arms and legs. Vascular flow studies, also known as blood flow studies, can detect abnormal flow within an artery or blood vessel.

What week is the color Doppler done?

The first fetal growth scan is suggested to be done between 28 weeks and 32 weeks of pregnancy to determine the growth and fetal wellbeing. The second growth scan and colour Doppler studies are done closer to the due date, which is between 36 and 40 weeks.
