The earlier the pubic bone pain, the easier it is to have a normal delivery. Whether or not you can have a normal delivery depends on the force of labor, the birth canal, the fetus and the mental state of the pregnant woman. 1. The force of labor refers to the power to deliver the fetus and appendages from the mother’s body, which is mainly related to the contraction force of the uterus, the contraction force of the abdominal wall muscles, the contraction force of the diaphragm, and the contraction force of the levator ani muscle. 2. The birth canal refers to the channel through which the fetus is delivered from the mother’s body, including the bony birth canal and the soft birth canal, relatively speaking, the soft birth canal is not abnormal, and the more spacious the bony birth canal is, the greater the possibility of a normal delivery. 3. The size of the fetus also has a great influence on normal delivery, such as the fetus is too large, which may lead to cephalopelvic disproportion, and the fetus can not be delivered through the birth canal. 4. The mental and psychological factors of pregnant women can affect the hormone level changes in the body, excessive fear and tension can lead to difficult labor, calm and relaxed mind is conducive to smooth labor. Whether or not a pregnant woman is able to have a normal labor needs to be evaluated by a professional physician to determine, to avoid blindly choosing to have a normal labor, so as not to lead to adverse consequences.
