Is the fetal heart rate of 147 a boy?

During pregnancy, some pregnant women will do fetal heart monitoring too early, which may not detect the accurate nuts. Experts say that the best time for pregnant women to start fetal heart monitoring is 32 to 34 weeks. From this time on, fetal heart monitoring can be done 1 to 2 times every week. Do not do it too frequently. In real life, people often use fetal heart rate to determine the gender of the fetus. So is a fetal heart rate of 147 a boy or a girl?

Is fetal heart rate 147 a boy?

There is a saying that the gender of the fetus can be determined by the fetal heart rate. If the fetal heart rate is lower than 140 beats/minute, it is a boy; if it is higher than 140 beats/minute, it is a girl.

The truth: Girls have a higher heart rate than boys, but this is only true when they are just born. There is no difference in the fetal heart rate between boys and girls.

The speed of heart rate only varies with gestational age. At about 5 weeks of pregnancy, the fetus' heart rate is close to the mother's heart rate, which is 80 to 85 beats per minute. Then, during the 9th week of pregnancy, the heart rate gradually increases to 170~200 beats/minute. Then during the second trimester, the rate gradually slows down to 120-160 beats per minute.

Normal fetal heart rate:

The normal fetal heart rate is 120-160 beats/minute;

Before 20 weeks of pregnancy, the average fetal heart rate is 162 beats/minute;

During the 21st to 30th week of pregnancy, the average is 147 beats per minute;

The average is 139 times/minute during 31 to 40 weeks of pregnancy.

Usually, the loudest fetal heartbeat is heard on the pregnant woman's abdominal wall above the fetus's back. Due to the different positions of the fetal head, the location of the loudest heartbeat is also different. It is beneficial for pregnant women to learn to count the fetal heart rate per minute. If the fetal heart rate is less than 120 beats/minute or greater than 160 beats/minute, it means that the fetal heart rate is abnormal and further review and monitoring are required.

Now that you know the fetal heart rate, it indicates a boy. When the fetus develops to 3 months, you can listen to the fetal heart rate to make a judgment. However, the method of judging the gender by listening to the fetal heart rate is not the most accurate. You may wish to combine some symptoms after your pregnancy to make a more detailed judgment, such as whether the taste is sour or spicy, etc., and combine them to judge the gender of the fetus.

Is the method of predicting the sex of the fetus accurate?

Many people try their best to know whether the baby is a boy or a girl. Some people think that fetal heart monitoring can show the gender of the baby. In fact, it is not true. We need to distinguish between them. And if we want to know the gender of the baby, we usually tell it.

Fetal heart rate monitoring is an important fetal heart rate project in the late pregnancy. When pregnant women do fetal heart rate monitoring, they can intuitively see the changes in fetal heart rate from the fetal heart rate monitoring chart to ensure that the fetus is in good condition. A fetal heart rate monitoring chart is provided below for expectant mothers to use as a reference.

There will be two curves on the fetal heart rate monitoring chart, one records the changes in fetal heart rate, and the other records the uterine contractions. Under normal circumstances, the fetal heart rate will be maintained at 120~160 beats/minute. The fetal heart rate will be faster when the fetus is active than when it is resting (at least 15 beats per minute) and last for at least 15 seconds. This normal situation is called "fetal heart rate monitoring reaction type", which is the result that every pregnant mother hopes to get.

If the fetal heart rate does not increase when the fetus moves, or there is no fetal movement at all during fetal heart monitoring, this means that the fetus may be in an abnormal condition (such as hypoxia or placental problems, etc.). This situation is called "unresponsive type" and the pregnant woman needs to do fetal heart monitoring again after 1 hour, or go for other further examinations.
