Cephalic position does not mean incarceration. Cephalic position means that the head of the fetus is facing downward, which is a type of fetal position. Pelvic insertion refers to the descent of the fetal head into the pelvic inlet, which has a different meaning. Cephalic position refers to the fetal position, indicating that the fetus is in a head-down position, which is conducive to pelvic induction and smooth labor and delivery, and is also a normal fetal position in late pregnancy. Pelvic insertion is the position of the fetus in late pregnancy surrounded by amniotic fluid and amniotic membranes, which allows the head to enter the pelvic cavity through the pelvic inlet of the mother and the position of the body to be consolidated. Pelvic entry can be in the cephalic position or in other fetal positions such as breech or transverse. Therefore, cephalic position does not mean that the fetus is in the pelvic position. After the fetus is in the pelvic position, the pregnant woman may have symptoms such as easier breathing, better appetite, perineal swelling, frequent urination, etc. It is necessary to go to the hospital and go through the examination in order to clarify whether the fetus is in the pelvic position or not, and your own arbitrary judgment may not be accurate. Do a good job of obstetric examination in late pregnancy, any abnormalities can be dealt with in a timely manner.
