The time of labor depends on the physical condition of the pregnant woman, the size of the fetus, the pelvic condition and other factors, so the specific situation varies from person to person. If a regular contraction occurs once every 5 minutes, it means that the woman has already entered into labor, at this time the cervix is generally shortened and flattened and the opening of the uterus is dilated at the same time, and the uterus can be prepared to deliver the baby when the opening is basically opened. As for the birth time, need to combine the strength of contractions and contraction duration to judge, due to the relative relaxation of the maternal birth canal, the delivery time is relatively short, generally will be within 6-8 hours of delivery. If the contractions are weak and last for a short time, or if the fetus is large and the pelvic condition of the pregnant woman is not good, the birth may be slower. If the contractions are strong and last for a long time, the fetus is small, the pregnant woman has a good pelvic condition and the fetal orientation is good, the birth will be faster. Therefore, if a pregnant woman has regular contractions during labor, it is recommended to go to the hospital in time for labor, relax, eat actively during labor, build up strength, observe whether there is vaginal bleeding or running water, and pay attention to fetal movement. If there is no vaginal flow or bleeding, you can take appropriate activities, such as walking and climbing stairs, to promote the progress of labor.
