Generally speaking, it takes about 10-11 hours for a primiparous woman to open her second finger, and about 5 hours for a transitional woman to open her second finger, but the exact time varies from person to person. The opening of the uterus by two fingers means that the mother has entered into labor and is in the latent phase of the first stage of labor. The degree of dilatation of the cervical canal during this period is related to the contractions, the degree of the uterus in the pelvis, the size of the fetus and the birth canal, and the opening of the uterus to 10 cm means the second stage of labor. During labor, the contractions change from irregular to regular and from short to long. Since labor is a gradual process, repeated contractions cause the cervical canal to recede and the fetus to descend, and the cervix is looser in menstruating mothers, so it takes about 11-12 hours for first-time mothers and about 5 hours for menstruating mothers after the cervix opens two fingers. However, the intensity of contractions and the size of the fetus vary from person to person, so the time required for delivery may vary. It is recommended that women pay attention to their diet during labor, eat chocolate for energy, try to choose easily digestible food, and ensure sufficient sleep.
