Abnormal fetal movement: After understanding the normal fetal movement, how to identify abnormal fetal movement? If the number of fetal movements in 12 hours is less than 20 times, or the number of fetal movements in 1 hour at night is less than 3 times, or the intensity of fetal activity changes significantly and becomes weaker and weaker, this indicates that the fetus may be abnormal and should be alerted. If the number of fetal movements is less than 10 times in 12 hours, or there is no fetal movement within 1 hour at night, it indicates that the fetus may be hypoxic in the womb, and you should go to the hospital for examination in time, otherwise it may lead to fetal death. In the initial stage of hypoxia, the fetus will become restless and struggle desperately. At this time, the fetal movement you feel will not decrease, but will increase. Therefore, if the fetal movement suddenly becomes abnormally frequent and exceeds 40 times, you should go to the hospital for examination in time. As the hypoxia continues, the restlessness gradually turns into suppression, so the fetal movement decreases, weakens, and disappears.

The length of a 9-month-old fetus is 45-48 centimeters, and the weight has increased by about 1,000 grams, which is about 2,500 grams. Subcutaneous fat began to appear all over the body, the body became round, there were more wrinkles, and the skin lost luster and color. The vellus hair covering the whole body has begun to disappear, and the fine hair on the eyelids and belly has disappeared. Nails grow quickly, reaching to but not beyond the tip of the finger. In boys, the penis descends into the scrotum, and in girls, the labia majora bulge, and the left and right sides are close together, that is, the genitals are almost complete.

By this time, the lungs and gastrointestinal tract are also well developed. Already capable of breathing, the baby drinks amniotic fluid and can secrete a small amount of digestive juice, and urine is also discharged in the amniotic fluid. Therefore, if the fetus is delivered at this time, it has the ability to grow in an incubator.
