Pubic bone pain in late pregnancy is not an aura of labor and it is not possible to determine the time of delivery. The time of labor needs to be judged by the intensity and duration of uterine contractions and the condition of the fetus of the pregnant woman. The reason for pubic bone pain in late pregnancy is due to the separation of the pubic bone due to the excessive pressure of the fetus or twin pregnancy. If a pregnant woman has a history of pelvic trauma or there is a serious calcium deficiency, it can cause pubic bone pain in late pregnancy. When a pregnant woman sees red or has regular abdominal pain with increased paroxysms, it is often a precursor to labor, at which time it is recommended to be hospitalized in time for delivery. Therefore, pregnant women should try to pay attention to more rest and avoid sitting and standing for a long time in the late pregnancy. You can take calcium supplements or use a belly brace to hold up the oversized abdomen.
