The position of the fetus is breech at 30 weeks of pregnancy, and it is possible that the fetus will turn, but the probability of the fetus turning on its own is not very high. If there is no indication for cesarean section and the umbilical cord is not wrapped around the neck, the fetal position can be corrected by lying on the chest and knees. The method is: the pregnant woman empties her bladder, loosens her pants, puts her chest and knees on the bed, and insists on fifteen minutes each time, once in the morning and once in the evening, and then reviews it one week later, the fetus may turn into the head position with the help of changing the center of gravity. It is generally recommended that after 36 to 37 weeks, after excluding contraindications to external inversion, the appropriate population is selected and the procedure is performed under close monitoring. Preoperative preparation for emergency cesarean section must be done under ultrasound and electronic fetal heart monitoring. This method carries a high risk and it is recommended to receive treatment in a regular hospital. It is recommended to have regular checkups during pregnancy and to follow the doctor’s instructions when abnormalities are detected, and not to take medication without authorization.
