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.
Hearing or seeing your babyâs tiny heart beating for the first time is an exciting moment. Your baby's heart starts beating when you're six weeks pregnant. Around the time of your dating scan, your babyâs heart is beating between 110 times and 160 times a minute. Thatâs about twice as fast as your heartbeat. You may also hear your babyâs heartbeat at one of your antenatal appointments. Your midwife is unlikely to listen for it while youâre still in your first trimester, as it can be hard to pick up at this stage. After your dating scan, the next time you hear your babyâs heartbeat may be during your 16-week appointment with your midwife.
