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.
Your baby's heart beats between 110 times and 160 times per minute. You may also hear your baby's heartbeat at one of your antenatal appointments. Your midwife is unlikely to listen for it while you're still in your first trimester, as it can be hard to detect at this stage. After this scan, the next time you'll hear your baby's heartbeat will probably be during your 16-week appointment with your midwife.
