A limited study for cervical length is a quick ultrasound to measure the length of your cervix during pregnancy.
Why is it done?
The scan checks that your cervix is the right length for how far along you are. It helps doctors see if you may go into early labor.
When do I get it?
Usually between 16-24 weeks of being pregnant. It can be later too. Your doctor may suggest it if you previously gave birth too early or have other risks. Only takes a few minutes to get the measurement.
Why get a cervical length scan?
How is the scan done?
The scan can be done through your belly or vaginally. For both, a small amount of gel is applied. For the belly scan, a transducer is moved over your skin. For the vaginal scan, a special probe is gently inserted and moved to get clear views of your cervix.
Do I need to prepare?
No special preparation is required. Just wear comfortable clothes that allow access to your belly if doing the abdominal scan.
What happens during the scan?
The sonologist will capture images and measurements of your cervix. This helps assess length and any changes. The whole appointment usually takes 15-30 minutes.
After the scan?
Your doctor will discuss the results with you and what they mean for your pregnancy. Be sure to book your next prenatal appointment to continue monitoring your pregnancy.
Hard copies of your reports will be available shortly once the scan is complete.

A cervical length scan is a simple ultrasound test that measures the length of the cervix during pregnancy. It helps assess the risk of preterm (early) labor by checking whether the cervix is shortening too early.
Cervical length is an important indicator of preterm birth risk. A shorter-than-normal cervix may increase the chances of early labor, allowing doctors to take preventive steps early.
The scan is most commonly performed between 16 and 24 weeks of pregnancy, but it can also be done later if your doctor feels monitoring is required.
This scan is recommended for women who:
Have a history of preterm delivery
Are carrying twins or multiple pregnancies
Have previous cervical surgery
Have symptoms like pelvic pressure or early contractions
Are considered high-risk pregnancies
It can be done in two ways:
Abdominal ultrasound (over the belly)
Transvaginal ultrasound, which provides the most accurate measurement and is completely safe during pregnancy
Yes, it is 100% safe. The probe does not touch the baby or uterus and does not increase the risk of miscarriage or infection.
A cervical length of 3 cm or more between 16–24 weeks is generally considered normal. Your doctor will interpret the results based on gestational age and risk factors.
If a short cervix is detected, your doctor may suggest:
Progesterone treatment
Cervical cerclage (stitching the cervix)
More frequent monitoring
These steps help reduce the risk of preterm birth.
No special preparation is required. You can eat, drink, and continue your routine normally. Wear comfortable clothing for easy access during the scan.
The scan usually takes 15–30 minutes. Reports are available shortly after completion, and your doctor will explain the results and next steps if needed.
