The eight-month-old fetus, whose organs have gradually matured, is usually in a head-down, curled-up position in the stomach. However, due to the different circumstances of individual pregnant women, it is impossible to generalize. In the eighth month of pregnancy, when all the organs of the fetus have matured, the biparietal diameter of the fetus is about eight centimeters, and its abdominal circumference is about twenty-six centimeters. The length of the fetus is about forty centimeters and its weight is about seventeen hundred grams. The small bronchial tubes and alveoli of the fetus are basically developed and have a certain degree of viability. The fetal position at this time is mostly head down and buttocks up, mostly indicating that the fetus is ready to enter the pelvis. If the position of the fetus is abnormal at this time, the pregnant woman can, under the guidance of the doctor, adopt the knee-chest position, so that the fetus can be converted to the correct fetal position. At the same time, pregnant women need to follow the doctor’s instructions for regular pregnancy checkups to observe the growth and development of the fetus. In the eighth month of pregnancy, do not engage in coitus at this time, so as not to stimulate uterine contractions, resulting in placental abruption and premature labor. Pregnant mothers are advised to maintain a happy mood to welcome the arrival of the baby.
