The seven-month belly is about 26cm high and the uterine fundus is about 3 horizontal fingers above the umbilicus. As the weeks of pregnancy increase, the uterus will gradually increase in size, which is reflected in the gradual increase in the height of the uterine fundus and the gradual expansion of the pregnant woman’s abdomen. However, the height of the uterine fundus varies depending on the distance between the umbilicus and the umbilicus, the development of the fetus, the amount of amniotic fluid and other factors. In the seventh month of pregnancy, the belly is about 26cm in height, which means that the fundus is about 3 horizontal fingers above the umbilicus. The rate of growth of the uterine fundus varies from week to week of pregnancy, and is generally highest at 36 weeks of gestation and decreases slightly at full term when the baby is in the uterus. The height of the fundus is usually measured after 20 weeks of pregnancy to give a general estimate of the number of weeks of pregnancy. It is also important to follow the doctor’s instructions for timely checkups during pregnancy, as well as early detection of fetal comorbidities or complications and timely intervention to ensure the safety of the mother and child.
