The sound of your baby’s heartbeat is one of the most thrilling experiences for expectant parents. Here’s everything you need to know about the development of this crucial system.
When Does Your Baby Develop a Heartbeat?
By the fifth week of pregnancy, the cluster of cells that will become your baby’s heart starts to form and beat. If you have an ultrasound performed in the first trimester, usually around week 6 or later, your healthcare provider will assess this early cardiac activity. This ultrasound will also help establish your estimated due date and confirm how many babies you’re carrying.
When Can You Hear Your Baby’s Heartbeat?
The chambers of your baby’s heart will become clearer on an ultrasound between weeks 17 and 20 of your pregnancy. If you’re curious about how to hear your baby’s heartbeat sooner, using a Doppler device can help, typically around 10 to 12 weeks into your pregnancy.
How Does the Fetal Heart and Circulatory System Develop?
Your baby’s heart and circulatory system undergo significant changes every week of your pregnancy, providing essential oxygen and nutrients. This development is vital for your baby’s growth and well-being.
