Precautions after 37 weeks of pregnancy are as follows: 1, self-counting fetal movements: once a week for labor and delivery, if it is normal, you can appropriately increase exercise to promote normal delivery; 2, weight control: usually the average weight of the fetus 3200g is the standard weight, so do not over-supplement during late pregnancy, and evaluate the weight of the fetus through ultrasound in a timely manner. If there is intrauterine growth restriction of the fetus, it is necessary to strengthen nutrition appropriately. If the weight of the fetus is in line with the gestational week, do not just supplement nutrition, because the delivery of a huge baby is likely to cause postpartum bleeding and also difficult deliveries, such as shoulder obstruction and cephalic obstruction, which will increase the rate of cesarean delivery. Therefore, it is recommended to manage the weight and count the fetal movements after 37 weeks, and be ready to start the delivery at the time of labor.
