If the week of gestation is accurate, a pregnancy that has not yet been delivered at 42 weeks is considered to be overdue and abnormal, and needs to be closely monitored and managed. If the measurement of the week of pregnancy is not accurate, the expected date of delivery should be re-estimated according to the ultrasound of pregnancy. If the fetus is not delivered at 42 weeks of pregnancy, pregnant women need to count the fetal movements and observe the fetal changes, and go to the hospital for ultrasound and fetal heart monitoring to check for abnormalities such as placental degeneration, low amniotic fluid and intrauterine hypoxia. In view of the fact that the chance of intrauterine hypoxia and obstructed labor increases at 42 weeks of pregnancy, it is not advisable to look forward to a further period of time, and it is recommended that the pregnant woman be admitted to hospital in time for delivery, and that measures such as induction of labor be taken to assist delivery according to the specific situation. Pregnant women should pay attention to maintain a calm state of mind, avoid anxiety and fear, and be prepared to welcome the newborn. You can take a walk or listen to music to help you have a smooth delivery.
