For primiparous women, labor is usually possible 2-3 weeks after the fetus enters the pelvis, while for menstruating women, labor begins immediately after the entry of the fetus into the pelvis. Fetal pelvic insertion is the first step in the labor process when the fetus descends into the mother’s pelvic cavity in a head-down, buttocks-up, full-body tucked-in position in late pregnancy, awaiting delivery. Generally speaking, for primiparous women, labor is usually possible 2-3 weeks after the fetus is in the pelvis; while for experienced women, labor begins immediately after the pelvis is in the pelvis, i.e., the fetus is in the pelvis and labor occurs at the same time. It is important to note that the timing of labor cannot be absolutely determined by the time the fetus enters the pelvis, as there may be large individual differences, and whether or not the fetus has entered the pelvis can only be determined after an antenatal examination. During pregnancy, pregnant women should eat more food rich in protein and more fresh vegetables and fruits to ensure a balanced intake of food and avoid single nutrition. Pay attention to more rest, at the same time should relax, avoid tension, anxiety, any discomfort should be timely to the hospital, by the doctor to clarify the diagnosis, and cooperate with the doctor to deal with the symptoms.
