Cervical Length Pregnancy Q&A

A cervical Ultrasound Scan is an ultrasound examination of the neck of your womb (cervix).
The cervical length should be more than 25mm.
An empty bladder is required for this Ultrasound Scan. Other than that, no specific preparation is needed.
Yes. None of the pregnancy Ultrasound Scans is harmful to you or the baby. Ultrasounds have been used for many years to monitor pregnancies. There is no radiation used in an ultrasound. It does not cause any health problems for the patient or the baby.
In London Private Ultrasound clinic, it is completed within 20 minutes.

The most accurate way to examine your cervical length is through transvaginal ultrasound. During this examination, you will be asked to lie on your back with your knees slightly bent, pointing towards your chest. You must remove all clothing from the lower part of your body as it is an internal female genitalia examination.

Your examiner gently and slowly inserts an ultrasound probe with a sterile and latex-free sheath and gel 2-3 inches (5-8 cm) into your vagina. Sound waves from the ultrasound send images to a screen.

The results are discussed verbally after your ultrasound and then sent to your email as a report on the same day.
It is not always necessary. However, your doctor may advise you to have this Ultrasound Scan if you previously had a premature delivery or a previous late miscarriage.
