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.
When Can You Hear the Baby's Heartbeat? Hearing your baby's heartbeat for the first time is an amazing experience that can boost your bonding with your baby. Expectant moms no longer have to wait for their baby to be far enough along for the doctor to use a stethoscope to hear their baby's heartbeat.
