It is possible to have a normal delivery even if the fetus is not in the pelvis at 39 weeks of pregnancy. Although first-time mothers are usually in the pelvis at 37-39 weeks of pregnancy, the timing of pelvic delivery varies from mother to mother, with some mothers having their fetal head in the pelvis after contractions, and most women in labor having their fetal head in the pelvis after delivery. The time of delivery alone does not determine whether the delivery will be successful or not, but needs to be considered together with the condition of the fetus and the status of the mother. The size of the fetus and the direction of the fetal position will affect the ability of the mother to have a normal delivery, and the size of the mother’s pelvis, i.e., its length, size, and elasticity, are also important for a normal delivery. If the size of the fetus meets the standard at 39 weeks, the fetal position is normal, the cephalopelvic area is proportional and the birth canal is suitable, it is usually possible to have a normal delivery. If the fetus has abnormal development (including too big or too small), or if there is fetal malposition or cephalopelvic disproportion, or if the birth canal is too long, small and inflexible, the mother can consider a cesarean section on the advice of the doctor. In short, the mother need not be overly anxious, depending on the situation, choose the appropriate mode of delivery to ensure the safety and health of the pregnant woman and the fetus.
