At 37 weeks of pregnancy, many women have vague abdominal pain. This condition is mostly due to the enlarged uterus, which makes the abdomen larger and causes pain due to compression of the surrounding tissues; the enlarged uterus may also cause straining of the ligaments around the uterus causing pulling pain. In addition, the fetal activity is frequent at this time, and the violent fetal movement and frequent fetal movement can also cause vague pain in the lower abdomen of pregnant women.
