It is normal to have no pain in the pubic bone at 38 weeks of pregnancy. Most of the pubic symphysis pain during pregnancy is due to fetal head compression, elevated levels of progesterone in the body, elevated levels of relaxin, and calcium deficiency during pregnancy. However, not all pregnant women experience pubic symphysis pain due to different body types, bone development, fetal size and orientation. At 38 weeks of pregnancy, the head of the fetus descends smoothly into the pelvic cavity, and the pressure of the fetal head on the pubic symphysis is relieved, so the pubic bone does not hurt. Calcium deficiency during pregnancy can cause pubic symphysis pain. During pregnancy, you should pay attention to timely calcium supplementation, avoid prolonged standing, and control your diet. Generally speaking, if the fetus is not too big, the pubic bone will not hurt at 38 weeks of pregnancy. If pubic bone pain occurs in 38 weeks of pregnancy, you should consult a doctor in time and give appropriate treatment under the guidance of the doctor.
