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 heartbeat of your baby? When searching for the baby's heartbeat, it is possible to hear the mother's heartbeat as well as the baby's, states Health & Parenting. The baby's heartbeat is much faster than the mother's, averaging between 120 and 160 beats per minute. Inability to hear the heartbeat should not cause concern as the position of the placenta, age of the fetus, amount of amniotic fluid, weight of the mother, and position of the baby can affect the ability to hear the heartbeat using a stethoscope.
