Labor pains after full-term pregnancy are usually lower abdominal pains because the uterus is located in the lower abdomen. Pregnant women can feel their lower abdomen with their hands, and they can feel the position of the uterus, which is hard when contracting, and they may feel pain with the hardening, and they also need to identify whether it is pain in the middle of the lower abdomen, or pain on both sides, or even pain in the lower part of the pubic bone or groin pain in the lower abdomen. Some pregnant women have constipation and may have intestinal distension in the rectum and colon, causing intestinal cramps. The pain is different from the labor contraction pains, which are spasmodic and transient colic, and may feel like defecation, and the pain is relieved after defecation. The pain is generally tolerable, and the intensity of the pain may become stronger as the opening of the uterus opens up during labor. When this kind of pain occurs, you should go to the hospital for hospitalization immediately.
