If a woman’s menstrual cycle is normal, every four weeks is counted as a gestational month. After 38 weeks of pregnancy, it is a full-term pregnancy, so it is necessary to prepare for delivery at 38 weeks of pregnancy. In the 38th week of pregnancy, we need to do: a. Obstetric ultrasound to observe the fetus, placenta and amniotic fluid, to observe whether the fetus is mature and the amount of amniotic fluid; we also need to do fetal heart monitoring, also known as NST, to see if there is intrauterine fetal hypoxia, if the fetal heart monitoring is reactive, it generally proves that the fetus is safe during the week and there is no intrauterine asphyxia. Secondly, blood tests such as routine blood test, blood type, hepatitis B, hepatitis C, syphilis, AIDS, hepatitis C and electrocardiogram will be taken to prepare for the delivery. If a woman is suspected of having placental implantation or is positive for rare blood types and irregular antibodies, it is also necessary to prepare in advance for the delivery appointment. Under normal circumstances, pregnancy is 40 gestational weeks and it is normal to deliver two weeks before or after the due date. It is important for women, whether they have a first or second child, to be prepared for delivery at 38 weeks of pregnancy.
