To keep tabs on your baby’s growth and health, 10BabyGear has put together this article to assist parents looking to understand what to expects about a baby and about the baby’s heartbeat over the pregnancy term.

If you are unsure about the term or the estimated delivery date of your baby, you can check use 10BabyGear’s delivery date calculator.

Baby Heartbeat at 6 Weeks

Part of week 5 and 6, a fetal heartbeat may be detected by vaginal ultrasound. Fetal doppler or home doptone may not be able to detect the heartbeat fully at this week. A lump of 2 to 4mm in length may not be producing sound waves that are detectable by home dopplers. The beats per minute at 6 weeks should be around 90 beats per minute.

No Sound of Baby Heartbeat at 6 Weeks. Should You Worry?

If you do not hear the baby’s heartbeat at 6 weeks, should you worry? In the video below, Dr. Teena Thomas from Doctor’s Circle answers this question:

Before we go into specific pregnancy weeks before and after 6 weeks, below is a helpful video by the British Heart Foundation explaining when you can start hearing the first heartbeat:

Week 1 and 2: Gestation

This is considered the gestation weeks and the period when the sperm penetrates into the egg with the sole purpose of fertilizing it. It takes a number of days for the sperm to travel in the fallopian tube and actually reach the egg.

Week 3, 4 and 5: Development

In week 3 and 4, the endometrium lining thickens and this is in preparation of the baby’s home over the next several weeks. Ultrasound may not be able to deduct any growth or any living being but transvaginal ultrasounds may detect gestational sac.

Below is a video that summarizes the development of the baby between week 1 and four:

Week 7

On week 7, a heartbeat can now be detected and it may range from 90 to 110 beats per minute. At this stage, you the chances of pregnancy success goes up to almost 90%.

From week 7 henceforth, you should be able to hear your baby’s heartbeat using a home fetal doppler or using ultrasound in the hospital. You can read more about the different fetal dopplers available and how you can safely use it to listen to your baby’s heartbeat at home.

You should note that from week 12 you won’t have to struggle as you try to hear the baby’s heartbeat as the baby’s heartbeat would have developed and the home doptone will be able to capture every beat.
