Where does labor contraction hurt?

I am about to go into labor, but I have not been sure where the contractions are. Where is the pain in the contractions?

Labor contractions are mainly caused by abdominal pain, but due to individual differences, some pregnant women have more obvious pain in the uterine fundus and lower uterine segment, as well as waist pain Symptoms of discomfort. As labor approaches, the interval between labor contractions of pregnant women becomes shorter and shorter, and the duration will gradually prolong, accompanied by dilation of the cervix and decreased fetal presentation. Pregnant women should maintain a calm and comfortable state of mind before giving birth, avoid excessive tension and anxiety, adjust their breathing rhythm, and eat properly to replenish their physical strength.
