The likelihood of the fetus starting on its own after the due date depends on the specific situation. If the position of the fetus is correct, the likelihood of it starting naturally is higher. It is normal for the fetus to start within two weeks before or after the due date. If there is no sign of the fetus starting after 42 weeks, or if there are problems such as cloudy amniotic fluid or aging placenta after the due date, it is necessary to consider using oxytocin under the guidance of the doctor to help the contractions to start. If the fetus has not started by the 40th week of pregnancy, but the placenta is normal, amniotic fluid and other aspects are normal, pregnant women do not need to worry too much, and wait for the natural start. It is recommended to go to the hospital one week after the due date for a routine checkup to determine how the fetus is doing and whether or not it needs to be induced, and to follow the doctor’s advice.
