One of the most exciting things about finding out you’re pregnant is hearing your baby’s heartbeat. It’s a sure sign that your baby is growing and developing as they should be. But how soon can you expect to hear that precious sound? Let’s dive in and explore the timeline of when a baby develops a heartbeat.

Week 4: The Beginning

At just four weeks after conception, your baby is still considered an embryo. It’s at this point that the heart begins to form. The heart starts as a simple tube, but it quickly divides into different chambers and begins to beat. While you won’t be able to hear the heartbeat yet, this is an exciting time as the foundation for your baby’s heart is being laid.

Week 5: The First Beats

Around week five of pregnancy, your baby’s heart will start to beat for the very first time. It’s still very early in development, so the heartbeat may be too weak to hear. However, it can be seen on an ultrasound. The heart rate at this stage is usually around 80 beats per minute.

Week 6: Picking Up Speed

As your baby grows, so does their heart. By week six, the heart rate will have increased to around 100-130 beats per minute. This is still too early to hear the heartbeat with a stethoscope, but it can be seen on an ultrasound. At this point, the heart is still very small and located close to the center of the chest.

Week 7: Audible Heartbeat

Around week seven, the heartbeat will become strong enough to hear with a Doppler ultrasound. This is a special type of ultrasound that uses sound waves to create a picture of your baby’s heart. You may also be able to see the heartbeat on a regular ultrasound at this point. The heart rate should be between 120-160 beats per minute.

Week 12: Fully Formed Heart

By week 12, your baby’s heart will be fully formed and functioning as it should be. The heart rate will continue to decrease slightly as your pregnancy progresses, but it will still be in the normal range. You’ll be able to hear the heartbeat at each prenatal appointment, and it will likely bring a smile to your face every time.
