ultrasound scan on monitor


Peace of mind for expectant mothers from 14 weeks. This scan is usually performed during pregnancy to assess the risk of preterm birth.


A cervical length scan is a prenatal test that assesses the length of your cervix to determine if it is prepared for the birth of your baby. During most of your pregnancy, your cervix remains closed and will only begin to open when your body is ready for delivery.

If your cervix is shorter than the usual length of 25mm, you may be at risk of preterm birth. This can be a concern for pregnant women who want to prevent preterm birth.

The scan will analyze the length of your cervix, as well as the dilation and location of the cervical suture (if present). If you are pregnant with twins, the length of your cervix is particularly significant.

The best way to measure the cervix is through a transvaginal ultrasound. The ultrasound transducer used in this screening test is designed to be painless.

Wear a two-piece outfit: You’ll need to undress from the waist down for the scan, so it’s best to wear a two-piece outfit like a top and trousers or a top and skirt. This will make it easier for you to get ready for the scan.


Empty your bladder: You’ll need to have an empty bladder for the scan, so be sure to use the restroom before your appointment.


Take any medication as usual: You can continue taking your regular medication before the scan.


Relax: While a cervical length scan may sound intimidating, it’s a routine procedure that is designed to be painless. Just relax and let our expert sonographers guide you through the process.

  • How early can I have a pregnancy scan?
    The earliest scan you can have an early pregnancy scan is from 6 weeks. Earlier than that and we might not be able to detect the baby’s heartbeat.
  • How accurate are early pregnancy scans?
    The early assurance scans are highly accurate when performed at the appropriate stage of the pregnancy (from 6 weeks onwards). The accuracy also relies on the scan being performed by competent and qualified sonographers. Early pregnancy scans are especially accurate when performed trans-vaginally because the scan images obtained in this manner can show a significant amount of miniature developmental details of the early pregnancy stages.
  • Are early pregnancy scans safe?
    Early pregnancy scans are performed by ultrasound, just like any other pregnancy scan. The only difference with early scans is that they are often transvaginal as opposed to abdominal – the procedure is completely safe for mother and baby.
  • When will I get the results for my reassurance scan?
    You will get the results of your ultrasound the same day as your appointment. You will also receive a typed report on email to keep for your records.
  • Can early ultrasound scan detect if I have twins?
    Yes, during in your early scan, you will be able to find out how many babies you will be expecting.
  • If the early pregnancy scan shows my baby is more likely to have a condition, what happens next?
    We have clear referral procedures to the NHS Trust Hospitals. To pursue the referral pathway, we contact the EPM Department at your trust hospital on your behalf, initially. Then we give you their contact number and our official referral form to present to them.
  • Can I find out the gender of my baby during early pregnancy scan?
    No, you will not be able to find out the gender of your baby during an early scan. You will be able to find out the gender of your baby from 15 weeks and 4 days.
  • When do you recommend having an early scan to learn as much as possible about my baby?
    We recommend that an early scan should only be performed 6 weeks after the first day of your menstrual cycle. Ultrasound is not able to demonstrate conclusive results of a viable pregnancy prior to this time. Attending an early assurance scan too soon can result in causing unwarranted worry since the results on the day would be inconclusive and require a second visit to the clinic for a reassessment. It’s important to just ensure you book the scan at the correct time frame to get the most reassurance and information about the pregnancy.
  • Can an early scan detect my baby’s heartbeat?
    Yes, from 6 weeks' gestation we will be able to detect your baby’s heartbeat via a transvaginal ultrasound. This is completely safe for your baby when performed with the correct equipment and by a competent sonographer.
  • If I can’t see my baby during early scan, what happens next?
    If you can’t see your baby during your early scan, we will organise a rebooking of your scan completely free of charge.
