Shallow pelvic entry means that a small part of the head of the fetus has entered the pelvic inlet and the fetus is not completely fixed. If there is a shallow pelvic entry, it means that only a small part of the head of the fetus has entered into the pelvic inlet area, and the fetus is not fully immobilized yet. In general, it takes about 2 to 3 weeks for the head of a primiparous woman to fully enter the pelvis, during which false contractions, appropriate activities, and exercise can promote the fetus to enter the pelvis. In the late stages of pregnancy, the fetus will appear to enter the pelvis, waiting for the right moment in a head-down, arm-up, whole-body-curled position. The head of the fetus enters the pelvic cavity through the pelvic inlet of the mother before delivery, allowing its body position to be fixed so that it can enter the birth canal smoothly during delivery. Late pregnancy should pay attention to rest, to prohibit sexual intercourse, on time maternity examination, if there are regular contractions, abdominal pain see red and other signs, it is recommended to go to the hospital to wait for labor.
