The time from cervical immaturity to ripening varies from person to person, a shorter time could be about 12 hours, if longer it could be 6 to 8 weeks. Cervical ripening is the process by which the cervix gradually softens, shortens, disappears, and dilates at the beginning of labor. Generally before labor, a large amount of prostaglandins will be secreted in a woman’s body, which can promote cervical ripening, change the morphology of cervical cells, and play a role in softening the cervix. Generally, the cervix is gradually ripening, which means that labor is imminent, and the closer the day of labor is, the more ripe the cervix will be. Generally, cervical ripening is a necessary checkup for pregnant women before delivery. The doctor will check the cervical opening, the degree of shortening of the cervical canal, and the hardness of the cervix to determine the degree of cervical ripening. Therefore, it is recommended to go to a professional hospital and let the doctor perform the examination before delivery, rather than doing it by yourself.
