If the amniotic fluid at 40 weeks of pregnancy does not start and the situation is stable, you can continue to wait for labor until 41 weeks to be admitted to the hospital, when abdominal pain, redness and other symptoms need to consult a doctor in a timely manner. If the ultrasound at 40 weeks of pregnancy indicates that the amniotic fluid is abundant and has not yet started, and the fetal heart and fetal development are normal in the labor and delivery examination, you can continue to wait for delivery, reduce the activities appropriately to avoid the occurrence of premature rupture of membranes and other complications, and be hospitalized until 41 weeks of labor and delivery examination on time. The doctor will give a small dose of oxytocin to induce labor after full evaluation and closely observe the progress of labor. When symptoms such as abdominal pain and redness occur during labor, consult the doctor promptly. After 40 weeks of pregnancy, the function of the placenta will gradually decline, so during the waiting period, you should also strictly count the fetal movement, and under the guidance of the doctor to regularly review the ultrasound to understand the changes in amniotic fluid and fetal growth, and go to the hospital in a timely manner when there are abnormal fetal movements and premature rupture of membranes.
