In general, you will be able to hear your baby's heartbeat when you are about 8 weeks pregnant using an obstetrics ultrasound. Or you may be able to hear the baby's heartbeat during regular prenatal care visit at 10 weeks, or more commonly at 12 weeks, with a fetal Doppler. The new fetal care technologies now allow for a much more specific time frame. We now know that your baby's heart begins to beat around 6 weeks after conception.
How soon can my babyâs heart beat be heard? Prenatal Testing No comments Your babyâs heart begins beating around 22 days after conception, about 5 weeks after your last period. At this stage, the heart is too tiny to hear even with an ultrasound. However, it may be detected as early as 4 weeks after conception as a flickering in the chest via ultrasound. After 9 or 10 weeks of pregnancy, you might be able to hear your babyâs heartbeat. Typically your physician will use a Doppler instrument to do this. A Doppler instrument bounces sound waves off the fetal heart. These sounds return, affected by what they bounced off of, and the changes in these waves are picked up by the receiver in the Doppler.
