It is normal for normal labor to start 1 week before or 1 week after the due date. If labor does not start 1 week after the due date, the doctor will recommend an injection to induce labor. If the fetus is not delivered beyond the labor period, all the examinations are normal, amniotic fluid is not less, pregnant women are not combined with gestational hypertension, gestational diabetes, etc., usually do not need to be dealt with, waiting for natural labor can be normal delivery in the due date 1 week in advance or delayed 1 week are normal phenomena. If the due date is delayed more than 1 week pregnant women still do not have contractions, then continue to wait for labor may be too large fetus, amniotic fluid reduction, placental failure and other conditions, which will lead to fetal hypoxia distress, will increase the risk of surgery. At this point, the doctor will recommend an injection of oxytocin, i.e. contractions, to stimulate the uterus to induce contractions and start labor. In addition, when the fetus is not delivered beyond the due date, it is recommended that the pregnant woman walk around more, which is conducive to the birth of the fetus.
