How long it will take for the uterus to open two fingers to be able to give birth needs to be specifically assessed according to whether it is a transient or primiparous woman, the size of the fetus, the force of delivery and other factors, and cannot be generalized. For pregnant women with two fingers open, no abnormalities in the birth canal, no factors that make labor difficult, and normal contractions, menstruating women can usually deliver in about 4 to 6 hours. For primigravid women, the uterus has opened two fingers, which generally means that the uterus is dilated by 3cm, at which point it just enters the active phase, and the labor is usually delivered in about 8 to 10 hours. In the case of painless labor, the duration of labor may be prolonged. If the fetus is relatively large, or if there is an abnormality in the birth canal, and the pregnant woman’s labor force is weakened, the uterine opening may not be able to deliver normally through vaginal delivery even if it opens normally, and if necessary, it will be necessary to deliver the baby through cesarean section.
