The pain of prenatal contractions varies from person to person and is usually moderate or above, and most women can barely tolerate it. Contraction pain is mainly in the lower abdomen and the two inner femurs or lumbosacral area, similar to menstrual pain, but more intense. Generally, the contraction pain is 3 to 5 minutes, a pain of 30 to 40 seconds, and the interval is getting shorter and shorter, the duration of the pain is getting longer and longer, the specific pain varies from person to person. After labor, there will be regular contractions, accompanied by dilatation of the uterine opening and the descent of the baby’s first sign. Although the prenatal contraction pain is sometimes severe and lasts for a long time, it is still a normal physiological pain and can be tolerated by most mothers. It is recommended that mothers should maintain a good state of mind during labor, avoid shouting, and exert themselves reasonably under the guidance of the doctor, so as not to cause poor uterine contractions that may lead to fetal asphyxia and other complications.
