The cervix is a very important organ in the female body, but not every woman's cervix is the same, and because the cervix is different, women's pregnancy is also affected differently. After pregnancy, women's bodies undergo many changes, the most typical manifestation of which is hormonal changes, and the length of the cervical canal gradually changes subtly with the increase of pregnancy time. So what is the length of the cervical canal considered to be about to give birth?
During prenatal check ups, mothers usually undergo B-ultrasound to measure the length of their cervix. If the cervix length is found to be over 30 millimeters, it is considered normal and generally does not result in premature birth; But if the cervical length is found to be below 30 millimeters, especially below 25 millimeters, attention should be paid to the possibility of premature birth. If the length of the cervical canal of the mother is between 15-24 millimeters, it is about two days before delivery; If the length of the cervical canal of the mother is less than 15 millimeters, it means that the delivery time is less than half a day.
If the cervical canal gradually disappears, it indicates that labor is about to begin, and the cervix will expand with the disappearance of the cervical canal. At this time, the mother should not be too nervous, but should relax and prepare for childbirth. Normally, the cervical canal is about 2.5-3 centimeters long, and its length does not decrease with the delay of pregnancy. Therefore, mothers should rest assured and cooperate with doctors to do various examinations.
