“The birth of a child in October is supposed to be the biggest and happiest event for a family. Under normal circumstances, a fetus will be conceived in the mother’s womb for ten months. Four weeks is one gestational month, and the whole pregnancy is forty weeks, which is ten gestational months in total. However, it is not uncommon for the delivery to take place two weeks before or after the due date. In other words, it is normal to give birth at 38 weeks of pregnancy. Generally, after 38 weeks of pregnancy, the fetus is basically mature and is ready for delivery. The average fetal length is about 47.5cm, the average fetal weight is 3100g, the average biparietal diameter is 9.08±0.59cm, the average abdominal circumference is 30.63±2.83cm, the average femur length is 7.20±0.43cm, which means that the fetal weight at this gestational week should be a little more than six pounds. If the placenta is not yet mature, the fetus may continue to grow, but the 38th week of pregnancy is already in the late stage of pregnancy, as the placenta gradually ages, it does not provide sufficient nutrition to the fetus, that is to say, although the fetus grows, but it is not too obvious, and there is a significant difference from the usual. Some fetuses may grow about half a pound between 38 weeks of pregnancy and delivery, but this is also very much related to maternal factors. Nowadays, the living conditions are good, the pregnant women usually have more than enough nutrition, the general fetal development of nutrition are in excess of the problem. If after 38 weeks of pregnancy, and then strengthen nutrition, if the fetal development is too rapid, may be caused by the fetal weight is too large, thus affecting the normal smooth delivery, this point is also need to pay attention to. In the pregnancy must ensure that the nutritional needs to facilitate the development of the fetus, but also try to avoid the problem of excess nutrition, otherwise not only is not conducive to the development of the fetus, but also not conducive to childbirth and the health of the mother herself. After the 38th week of pregnancy, the day of delivery is getting closer and closer. The weight of the pregnant woman has increased by about 10.9 kg, the height of the uterus is between 30.5 cm and 38.5 cm, the circumference of the abdomen is between 89 cm and 100 cm, and in the last weeks of pregnancy, the hands and feet of the pregnant woman look very swollen, which is normal and will disappear after the delivery. It is important to have proper activity during this period so that it will facilitate the delivery.
