Regular contractions are a sign that a woman is in labor. If a pregnant woman has progressively more frequent contractions, the interval between two contractions becomes shorter and shorter, from 25 minutes to one contraction in an hour lasting for several minutes, to contractions with a frequency interval of 4-5 minutes lasting for more than 30 seconds. If a contraction of 5 minutes, lasting 30 seconds, is gradually shortened to one contraction of 3 minutes, lasting 60 seconds, while the intensity of the contraction increases, it means that the baby is about to be born. However, there is still some time before the pregnant woman really enters into labor. Most pregnant women are within 24 hours from the appearance of regular contractions to the end of labor. If there is no labor for more than 24 hours, it is considered stalled labor, and other methods of labor should be taken in conjunction with the specific situation to avoid adverse consequences. In late pregnancy, pregnant women are advised to monitor their contractions. Occasional irregular contractions may occur during pregnancy, but if they are regular, they must be hospitalized for labor. Close monitoring of fetal movements should be observed during labor and delivery; normal fetal movements should be 3-5 times per hour. The frequency of contractions can be judged by the four-step palpation method or by doing fetal heart monitoring examination. The duration, interval and intensity of the contractions can be clearly seen on the fetal heart monitoring graph. Also, when contractions occur, it is important to note if there is redness or vaginal fluid. Also, if there is soreness in the lumbosacral region, which is significantly worse, accompanied by contractions with gradual opening of the uterine opening and fetal head descent, it indicates that labor is imminent. During hospitalization, the doctor will perform an internal examination and note the state of the cervix. For primigravida, the opening of the uterus is 6 cm and the baby needs to be sent to the delivery room for a pending examination. For menstruating mothers, they need to be sent to the delivery room when the opening of the uterus is 2 cm wide because labor is fast. Pregnant women should not be overly nervous and relaxed, which can contribute to a smooth delivery.
