Contractions once every 5 minutes can be regarded as a sign of labor, and generally pregnant women will give birth within 24 hours, but the specific time of delivery varies from person to person, and is related to whether or not the woman is a first-time mother, the specific position of the fetus, and the state of laxity of the birth canal, etc. 1, primiparous women: for first-time pregnant women, the period from the beginning of the contractions to the completion of the birth will last about 12-18 hours, and if the position of the fetus is appropriate, and the size of the fetus is appropriate, and the birth canal is more lax, the duration of labor is usually a little shorter. If the position of the fetus is suitable, the size of the fetus is moderate, and the birth canal is loose, the duration of labor is usually shorter. Therefore, the mother can eat or rest in between contractions to save her strength for labor. During this period, the mother can walk or move around moderately, which will be conducive to the opening of the mouth of the uterus to speed up the process of labor; 2. Experienced mothers: pregnant women who have given birth for the second or more times may have a faster progress of labor, and the labor can be delivered in 6-7 hours usually. Therefore, pregnant women who feel regular contractions, or even redness and water breakage need to go to the hospital in time to wait for labor to ensure the smooth delivery of the fetus. Regular contractions are a sign of labor and the strength of the contractions is closely related to the speed of dilatation of the uterine opening. If the contractions intensify slowly and last for 30 seconds, with 5-6 minutes in between, accompanied by the opening of the uterus and the descent of the fetal head, it means that labor is in progress. Pregnant women are advised to adjust the rhythm of breathing and maintain a stable mood. If the contractions are too long and the labor is still not successful, it may lead to intrauterine distress, and the doctor will recommend timely Caesarean section or vaginal delivery to avoid fetal asphyxia.
