It is not possible to say for sure when the fetus will be born after it has entered labor, because there is no necessary connection between labor and delivery, and the timing of labor varies greatly among pregnant women. Some pregnant women can be in labor between 30 and 34 weeks of pregnancy, but being in labor doesn’t mean that they will go into labor at that time. The majority of pregnant women will be in labor after 38 weeks, which is a prerequisite for labor, but it’s not certain when they will go into labor after being in labor, and a few pregnant women don’t go into labor even when they are due, which means that we need to evaluate whether there is cephalopelvic disproportion. There is no fixed link between the time of labor and the time of delivery. If labor occurs too early, you should be alert to the possibility of preterm labor, and then you need to keep the baby in labor. If the baby has not entered the pelvis by the time labor is imminent, you need to assess whether there is cephalopelvic asymmetry, and if there is obvious cephalopelvic asymmetry, it is recommended that you have a cesarean section to end the labor in time.
