How to calculate the number of fetal movements

Fetal movement is a phenomenon that women must pay close attention to during pregnancy, because if there are abnormal fetal movements, it is very likely that there are certain problems with the baby's development. If you want to understand the fetal movement, in addition to going to the hospital for examination, pregnant mothers can also count the number of fetal movements at home. So, how do you calculate the number of fetal movements? This will be introduced below!

1. How to calculate the number of fetal movements

1. Record the time required for 10 fetal movements

Fetal movements are more frequent after dinner. At this time, the expectant mother can adopt the left side lying position and record the time required for 10 fetal movements. If the time required for 10 fetal movements is less than 120 minutes, it means that the number of fetal movements is normal; if you do not feel the fetal movement or the time required for 10 fetal movements is more than 120 minutes, you should go to the hospital for examination as soon as possible.

2. Calculate fetal movements within a fixed time

Expectant mothers can also count fetal movements for one hour each in the morning, noon and evening. There should be no less than 3 times per hour. Multiply the total number of fetal movements in 3 hours by 4, and the result should be no less than 30 times. If there are less than 10 times, it means it is abnormal and you need to see a doctor as soon as possible.

2. How many fetal movements are normal?

Under normal circumstances, after 28 weeks of pregnancy, the fetal movement is about 3-5 times per hour, and the number of fetal movements in 12 hours is about 30-40 times. If the fetal movement is less than 3 times per hour, it often means that the fetus may be suffering from hypoxia and should not be taken lightly.

It is also important to note that the strength and frequency of fetal movements during the day and night are different. There will be fewer fetal movements in the morning, which will increase after 6 pm. Fetal movements are most active between 8 and 11 pm. This is actually the sleep pattern of the fetus, which we call the fetal biological clock. In addition, the strength and frequency of fetal movements vary greatly from individual to individual. Some may move more than 100 times in 12 hours, while others may only move 30-40 times. But as long as the fetal movement is regular and rhythmic, and the changing curve is not large, it means that the fetal development is normal and there is no need to worry.

3. Abnormal fetal movements that need to be watched out for

1. Decreased fetal movement

The sudden decrease in fetal movement may be because the expectant mother has a fever, which increases the blood flow around the body, reduces the blood flow to the placenta and uterus, and causes slight hypoxia in the fetus. Generally speaking, in this case, the fever is more serious and it is recommended to seek medical treatment.

2. Fetal movement is late and weak

For some expectant mothers, fetal movements occur at irregular intervals and are relatively weak. This may be caused by placental insufficiency, which can lead to insufficient oxygen to the fetus. Long-term hypoxia slows down fetal movements.

3. Fetal movement stops suddenly after rapid movement

This situation often occurs after the second trimester, especially in expectant mothers who suffer from high blood pressure, severe trauma or short-term reduction of intrauterine pressure. Symptoms include vaginal bleeding, abdominal pain, uterine contractions, and severe shock. In addition, this situation may also occur if the fetus is accidentally caught in the umbilical cord when rolling, resulting in blood flow.
