The fetus has entered the late stage of gestation at 28 weeks, when the fetus is basically mature, with a biparietal diameter of about 7.5cm, a length of about 35cm and a weight of about 1150g. The subcutaneous fat of the fetus has begun to develop, and the amniotic fluid in the uterine cavity is more abundant during this period, and the fetal movement is more obvious and the amplitude of fetal movement will gradually increase. After 28 weeks of gestation, we should pay attention to check the blood sugar and blood pressure of pregnant women, if the blood sugar is elevated, we should pay attention to control it through diet and physical exercise to avoid producing a huge baby. Pregnant women should also have a balanced diet and limit salt appropriately to avoid hypertension during pregnancy. After 28 weeks, pregnant women need to start counting their own fetal movements at home to monitor the well-being of the fetus in the womb.
