There is no specific relationship between fetal insertion and the time of labor. A primiparous woman may give birth about 1-2 weeks after the fetus is in labor, and a transient woman may give birth 8-10 hours after the fetus is in labor. However, the time of labor is not certain for each individual due to individual differences. After the pregnancy, the primigravida usually enters the pelvis before initiating labor and delivery. It may be possible for the fetus to go into labor around 38 weeks of pregnancy, and after going into labor it may be possible to deliver around 40 weeks of pregnancy, so a primigravida may give birth around 1-2 weeks after the fetus goes into labor. A transient woman goes into labor later, and most fetuses may go into labor at term, so a transient woman may give birth about 8-10 hours after going into labor. If a primigravida does not have the fetal head in the pelvis at the time of labor, it may be a manifestation of a pathology caused by absolute cephalopelvic asymmetry or relative cephalopelvic asymmetry, and a cesarean section may be necessary to terminate the pregnancy.
