The time between contractions and labor varies with each person’s physical condition and the size of the fetus and pelvis. In most cases, it takes about 14 to 24 hours for a first-time pregnant woman, and about 6 to 8 hours for a second-time pregnant woman. 1. First-time pregnant women: The time from the onset of regular contractions to labor is longer for first-time pregnant women. Since the first-time pregnant women have no experience in labor, the cervical canal has a certain length, so they need to wait for the cervical canal to soften, disappear and flatten out, and the mouth of the uterus begins to dilate before they start to give birth. The size of the fetus and the condition of the mother’s pelvis should also be taken into consideration. In most cases, it takes about 14 to 24 hours. 2. Experienced pregnant women: Because of their previous experience in labor, the disappearance of the cervical canal and the dilatation of the cervical opening can be carried out at the same time during labor, and the time will be shorter than that of the first time pregnant women, and in most cases it will take about 6~8 hours. Pregnant women should adjust their mindset after contractions, avoid standing or walking for a long time, and take regular tests to prepare for labor.
