The time it takes to open the first finger to the tenth finger of a newborn woman depends on the woman’s physical condition, the strength of contractions, the toughness of the cervix, the degree of fetal head descent, etc. The exact time varies from person to person and cannot be generalized. The professional medical name for the opening of the finger is cervical dilation, from the opening of one finger to the opening of the whole, that is, the opening of ten fingers, called the first stage of labor, first-time mothers usually take 11-12 hours, at this time, without too much intervention, you can let the pregnant woman appropriate water and food, to relieve tension. Some first-time mothers need 15-16 hours, if the contractions are sparse or weak in the late stage, you can give contractions to induce labor. After labor, the opening of the uterus should continue to open to 10 fingers before delivery, but the exact time is not clear. During this period, it is recommended that the pregnant woman in first labor should maintain patience and strength and wait for the obstetrician to observe the opening of the uterus at all times.
