Ordinary stethoscope to listen to the fetal heart, need to wait until the large gestational weeks, such as full-term listening to listen to clear, need to maintain the correct position of the fetus.
It is difficult to find the fetal heart sound with a normal stethoscope, so it is seldom done in the clinic. The only way to find the fetal heart sound with a normal stethoscope is when the fetus is in a good position in the first trimester of pregnancy, and the back of the fetus is pressed against the belly of the pregnant woman.
The correct way to find the fetal heart sounds is usually to keep the pregnant woman lying down and place the small probe of the general stethoscope on the back of the fetus, and you may hear the fetal heart sounds as if a clock is ticking.
As it is difficult for the general public to listen to the fetal heartbeat with a stethoscope, it is advisable for the pregnant woman to go to a specialized hospital and be guided by a doctor.
