It is not accurate to use a homemade fetal heart monitor at home during pregnancy. You should choose a professional fetal heart monitor.

Before listening to the fetal heartbeat, let the pregnant woman urinate and lie flat on the bed. If the pregnancy is a little advanced, you can first check where the fetal back is, and then place a cylindrical stethoscope on the pregnant woman's abdominal wall to hear the fetal heart sounds. Before 24 weeks of pregnancy, fetal heart sounds are mostly heard in the center below the navel or slightly to the left or right; after 24 weeks of pregnancy, fetal heart sounds are most clearly heard on the side where the fetal back is.

Listening to the fetal heart rate is usually done by the husband or a family member. It can be heard by the husband using a trumpet-shaped wooden receiver. The fetal heartbeat is most clearly heard on the back of the fetus. It is generally located around the umbilicus, 2 inches above, below, left and right. Before listening to the fetal heart rate, it is best to empty your bladder first and lie on your back in bed with your legs straight. Ask your husband to gently place the wooden stethoscope on the part of the fetal heart that is clearest. Listen carefully and count carefully, one minute at a time, and write down the number of beats.

Generally speaking, the fetal heart rate can be detected at 20 weeks of pregnancy. It occurs later than fetal movement. The normal fetal heart rate is fast and strong, about 120-160 beats per minute. In the second trimester of pregnancy, the fetal heart rate can reach more than 160 beats per minute. In prenatal examination, listening to fetal heartbeat is an indispensable item. It can be used to judge the growth and health of the fetus. When the fetal heart rate suddenly becomes faster or slower, that is, when irregular conditions occur, it should be taken seriously. Pregnant women and their families can listen to the fetal heartbeats at home. They can place a stethoscope against the pregnant woman's abdominal wall to count the fetal heartbeats. When the fetal position is normal after 24 weeks of pregnancy, the correct position to listen to the fetal heartbeats is in the middle below the navel, or on the left and right sides of the navel. In the late pregnancy, the fetal heartbeat can be clearly heard by using a fetal heart stethoscope on the pregnant woman's abdomen and fetal back. The normal fetal heart rate is 120-160 beats per minute. It can be counted once or several times a day. Count for 1-2 minutes each time. If the fetal heart rate exceeds 160 beats/minute or is lower than 100 beats/minute, you should see a doctor immediately.
