Does the cervical length increase or decrease with gestational age?

Patient's question:

No

Doctor's answer:

Generally, cervical shortening indicates a possible premature birth. Cervical shortening and expansion usually occur only when nearing the late stage of pregnancy, close to delivery. In your case, a cervical length of 3 cm at 13 weeks is normal and not a problem. It does not qualify as cervical insufficiency. Later on, pay attention to abdominal pain and fetal movement. If you experience abdominal pain, take medication promptly to avoid stimulating cervical shortening and causing premature birth.
