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.
Most women first hear their baby's heartbeat during a routine checkup that uses the fetal Doppler early in their pregnancy. Many ultrasound machines also allow the heartbeat to be heard even before it can be heard with a handheld Doppler. Most women now get an ultrasound prior to 12 weeks.ost women first hear their baby's heartbeat during a routine checkup that uses the fetal Doppler early in their pregnancy.
