In the seventh month of pregnancy, the uterus is usually at the height of three horizontal fingers above the navel, and the upper abdominal circumference is usually about 90cm and the lower abdominal circumference is about 80cm, but there are some differences for each person. If the pregnant woman in the seventh month of pregnancy every day to eat more normal, and more obese body type, the baby in the uterus growth and development is also better, pregnant women may be on the large side of the belly to reach about 90cm. However, if the pregnant woman does not eat regularly every day during the seventh month of pregnancy or has a thin body type and the baby’s body grows and develops poorly in the uterus, it may result in a slightly smaller belly. So during the seventh month of pregnancy due to the different body types of pregnant women, the abdominal circumference of each person will be somewhat different. However, if during the physical examination during pregnancy, it is found that the indicators of the pregnant woman and the fetus are abnormal, such as excessive amniotic fluid, huge baby, etc., it is recommended to consult a doctor in time, complete the relevant examinations under the guidance of the doctor, clarify the cause of the disease, and treat the symptoms.
