You might need this scan if you have a history of late miscarriage, a multiple pregnancy, or have previously had surgery on the cervix.
A Cervical Length Scan is performed trans-vaginally for optimum clarity and results. This means that the sonographer will ask for your consent to insert an ultrasound probe into your vagina.
You will receive a clear written report of your scan results, including our recommendation for your next steps. If we recommend a medical follow-up, we can email a copy of your report to your healthcare provider at no extra cost.
For people over 16 years of age.

Frequently Asked Questions
On rare occasions we are unable to complete the primary purpose of a scan. For pregnancy scans, this may be due to your baby being in a difficult position, or something else such as overlying bowel gas which can obscure the ultrasound image. If this happens, we’ll book you a free of charge rescan so we can try again! The primary purpose is outlined on each scan webpage.
As healthcare professionals the health and wellbeing of you and your baby is our priority. There may be occasions when we need to discuss unexpected findings or bad news. If this happens during your scan, our team will ensure you receive the best possible compassionate care delivered to you as sensitively as possible.
We will also recommend your next steps. With your consent, we can contact the local early pregnancy unit or midwife on your behalf where possible. For general health scans, we can email our report and supporting images to your GP.
If after your scan you become concerned about the scan itself or your images and video clips, just call the clinic where you had your scan to discuss any concerns. If the clinic is closed, contact our head office who will be more than happy to help with your query.
Absolutely! Every scan at Ultrasound Direct is performed by a fully qualified sonographer whose primary interest is your health. All our sonographers are fully trained and appropriately qualified to perform ultrasound scans. Many of our team also work in the NHS locally.
We are also registered with the Care Quality Commission, an independent regulator, to make sure you always receive the highest possible standards of care.
All our sonographers who take blood for blood tests are phlebotomy trained.
If you are experiencing pain or bleeding, go directly to your local A&E or contact your midwife – do not book an ultrasound scan. This is because you may be experiencing a medical emergency and waiting for a scan will cause a potentially harmful delay.
Research suggests that there are no known risks to our method of ultrasound scanning. Scans are painless (although an internal scan may be slightly uncomfortable) and have no known side effects. Ultrasound scans do not use any form of ionising radiation, unlike other diagnostic imaging services such as x-rays.
During pregnancy scans, we can record your baby’s pulsebeat – this sounds very similar to the heartbeat, but is recorded in a different way. We record the pulsebeat by scanning blood flow through the umbilical cord, rather than recording the heartbeat by scanning the heart. This is because consistent ultrasound output in one place can have a heating effect, and we don’t want to put your baby at any level of risk. The fast-moving blood in the umbilical cord quickly disperses any potential heating effect.
