At 36 weeks of pregnancy, many pregnant women will experience pain in the pubic bone, which is mainly due to the enlargement of the uterus, pressing or touching the upper side of the pubic symphysis, resulting in obstruction of blood circulation and triggering pain. This does not mean that the pubic bone pain is going into labor at this time, because 36 weeks has not yet reached the time of the expected date of delivery, not yet full-term. If there is pain in the pubic bone, abdominal cramps, or even vaginal bleeding and redness, there is a possibility of preterm labor, or premature labor, and it is important to go to the hospital in time for a careful examination and specialized treatment. In addition, when a pregnant woman walks for a long time, her abdomen will squeeze the upper side of the pubic bone, causing pain. Pubic bone pain can occur if the pubic bone is injured, or if there are other reasons for it, but it does not mean that a woman of childbearing age at 36 weeks is going into labor right away.
