The time it takes for the uterus to open to ten fingers varies from pregnancy to pregnancy, and is generally longer for primigravid women, about 11 to 12 hours. The time required for a woman in labor is shorter, about 6 to 8 hours. Of course, this time is not absolute, some will be faster and some slower. The first stage of labor is from regular contractions to the opening of the uterus. The duration of the first stage of labor is related to the strength of the contractions, the strength of the cervix, and the degree of descent of the head of the fetus. The uterine opening will begin to dilate slowly and will gradually accelerate as the uterine opening opens to 4-6cm. Pregnant women entering cervical dilatation need to stay in the hospital for labor. Rest should be taken care of, and you can move appropriately when there is a break between contractions. You can consume a small amount of non-dregs diet to ensure that you have enough energy to be fully prepared for labor.
