Some factors that can affect whether you can successfully hear your baby’s heartbeat.
Stage of your pregnancy. Though a baby’s heartbeat may be heard with a Stemoscope by a medical professional as early as the 16th week, it is not easy for a mom to hear it because the heartbeat sounds can be very weak. You may wait until the 25th week to try.
Position of your baby. Your baby’s position affects whether the heartbeat sounds can be transmitted to the surface of the belly. If your baby’s heart is close to the belly surface, it is easy for you to hear his or her heartbeat. Otherwise, it may still be difficult for you to hear it.
Some patience. When you try it for the first time, if you don’t know your baby’s position, you may need to spend minutes after minutes to find a location on your belly where you can hear your baby’s hearbeat. There are also some expecting moms who are not able to hear their baby’s heartbeat in their first try. Consider the process to find the best listening location a way you learn and interact with your baby. When you learn to know your baby’s position, it would be easier for you to hear it next time.
