When the cervix opens, it is recommended that the pregnant woman be hospitalized for observation of labor. Clinically speaking, labor is defined as the contraction of the uterine cervix, the cervical canal begins to shorten, the cervical opening begins to open, and the first sign of the baby descends. Therefore, when there are regular contractions and the cervical opening has begun to open, the woman can be hospitalized. Although some pregnant women may be in false labor or preterm labor, and the contractions may disappear after a certain amount of rest, or there may be no regular contractions for a while, and there is still some time left before delivery, it is still recommended that they be hospitalized as soon as possible to wait for a normal delivery in order to prevent the labor process from starting, which may lead to panic and emergency situations.
