Can the cervical length get longer?

Patient's question:

No

Doctor's answer:

Hello, according to the situation you described, it is generally possible to determine the length of the cervix through ultrasound. If the cervical length is greater than 30 millimeters, it is generally unlikely to result in preterm labor; however, if it is less than this value, especially less than 25 millimeters, it suggests a higher likelihood of preterm labor.
