The time of labor from 3 fingers to 10 fingers varies from person to person, it takes about 6~8 hours for primigravida and 3~4 hours for transplants, mainly related to the strength of contractions, the number of deliveries, the size of the fetus and other factors, which need to be analyzed specifically. 1. The strength of contractions: If the contractions are regular and strong, the uterus will open faster, and vice versa. 2. The number of times of labor: generally speaking, the time from 3 fingers to 10 fingers will be relatively long for primigravid women, which takes about 6 to 8 hours, and it will be faster for experienced women, which may be 3 to 4 hours. 3. Fetal size: when the fetus is larger the time to pass through the pelvis is extended accordingly. The time of labor from 3 fingers to 10 fingers is also related to other factors. Pregnant women are advised to follow the doctor’s instructions during labor, push reasonably, and avoid blindly using brute force, so as not to cause damage to the birth canal.
