A: Your baby's heartbeat is one of the first things your doctor will look for on an ultrasound, a test that uses sound waves to give off visual images of your baby and placenta as well as your uterus and other pelvic organs.
If you donât have an early ultrasound, you probably have to wait to hear your babyâs heartbeat at a prenatal care visit via a Fetal Doppler. Your caregiver will usually be able to find the heartbeat with this method around 12 weeks, but in some cases they will do so at 10 weeks.f you are wondering, when does a fetus have a heartbeat? Remember that you might be able to see and hear your babyâs fetal heartbeat at around 8 weeks into your pregnancy during an early ultrasound. The actual heartbeat will begin around 6 weeks along.
