Tightness and hardness of the stomach, if there is no pain, indicates pseudo contractions. Pseudocontractions are the phenomenon of pseudocontractions after the fetus is moving inside the uterine cavity or after the ectoderm is stimulated, and are not a sign of imminent birth. If the pseudocontractions are more frequent after reaching the due date, they may trigger real contractions, which are the precursor of birth and need to be observed and distinguished. In general, false contractions are not regular, and there is no pain, but regular contractions will be followed by special regularity and obvious pain, which means that the birth is imminent. If the regular contractions are produced, the opening of the uterus should be fully opened in 10-13 hours, which means that the first stage of labor has been completed, and the baby will be born in the second stage of labor, and the fetal head will be delivered.
