Most precise dating method
In the first trimester, all babies grow at a similar rate. Measuring the crown‑rump length gives a due date within 3‑5 days of accuracy – far better than relying on your last period alone.
A dating scan is an ultrasound examination performed between 8 and 14 weeks of pregnancy. It measures your baby's crown‑rump length (CRL) – the most reliable way to establish your estimated due date (EDD) and confirm that your pregnancy is progressing normally.
Many women are unsure of their exact dates, especially if they have irregular cycles, conceived while breastfeeding, or simply lost track. A dating scan removes the guesswork, giving you and your doctor a solid foundation for all future antenatal care – from screening tests to induction planning.
At Amytri, we perform dating scans with precision and care. Our consultant radiologist takes detailed measurements, checks for a healthy heartbeat, and assesses the early anatomy. You'll receive a clear report with your due date, and we take the time to explain every finding in plain language.
Your due date is the cornerstone of your pregnancy care. A dating scan ensures everything is planned correctly from the start.
In the first trimester, all babies grow at a similar rate. Measuring the crown‑rump length gives a due date within 3‑5 days of accuracy – far better than relying on your last period alone.
Tests like the nuchal translucency (NT) scan, NIPT, and the anomaly scan must be performed at specific gestational ages. An accurate due date ensures you don't miss these windows.
A dating scan also checks that the baby's size matches the dates, giving you early reassurance that your pregnancy is progressing as expected.
Our dating scan is thorough, using precise measurements to give you confidence in your dates.
We measure your baby from head to bottom – this is the gold standard for dating in the first trimester. The measurement is used to calculate your due date with high accuracy.
We confirm the presence of a strong, regular heartbeat – a reassuring sign of a viable pregnancy.
We check for more than one embryo – twins are often identified at this stage, which changes your care pathway.
We evaluate your uterus for fibroids, the ovaries for cysts, and any other pelvic findings that could affect the pregnancy.
We assess the early amniotic fluid volume and the position of the placenta (if visible) to ensure everything is normal.
Based on the CRL, we calculate your EDD – the date you can expect your baby to arrive. This is the foundation of all your antenatal care.
Call or WhatsApp us to book – we recommend scanning between 8 and 14 weeks for optimal dating accuracy.
Drink water and avoid emptying your bladder for about an hour before the scan – this improves image quality.
We perform the scan on your abdomen. If needed, we may also use a transvaginal probe for better detail – both are safe and painless.
We explain your due date and findings on the spot, provide a written report, and give you printed images to treasure.
Even with perfect periods, a dating scan is a standard part of early pregnancy care. But it's particularly valuable in these situations.
If you don't remember the date of your last period, or your cycles are irregular, a dating scan is essential to establish your due date.
If you conceived while on the pill, or soon after stopping it, your cycle may be irregular – a dating scan gives you clarity.
When dates are known from the procedure, a scan still confirms the number of embryos and checks development, but dating is often based on the procedure date.
Early reassurance that your baby is growing as expected is invaluable if you've had a loss before.
If you experience symptoms, a dating scan can rule out miscarriage or ectopic pregnancy and confirm your dates.
Many couples find that a dating scan provides reassurance and helps them connect with the pregnancy – a wonderful early milestone.
Your dating scan is performed by a consultant radiologist with extensive experience in obstetric ultrasound – ensuring the highest precision in measurement and interpretation. We take pride in delivering accurate dates with a warm, supportive approach.
Seeing your baby on screen and hearing their heartbeat is a magical experience – we warmly encourage your partner to be part of it.
Our scan room is comfortable and private, with a large screen so you can both watch. We explain every measurement and what it means, answer all your questions, and give you printed images to take home. It's a moment you'll remember forever.
A dating scan is an ultrasound performed between 8 and 14 weeks of pregnancy to accurately determine your baby's gestational age and your estimated due date (EDD) by measuring the crown‑rump length (CRL).
Yes. A viability scan (6‑10 weeks) primarily confirms a heartbeat and rules out ectopic pregnancy. A dating scan (8‑14 weeks) focuses on measuring the baby to give you the most accurate due date – though both check viability.
In the first trimester, the crown‑rump length measurement gives a due date within 3‑5 days of accuracy – much more reliable than relying on your last menstrual period.
No referral is required. You can book directly. If you're under obstetric care, we'll share the report with your doctor.
For an abdominal scan, we ask you to come with a comfortably full bladder – this helps push the uterus up for a clearer view. For a transvaginal scan, you'll be asked to empty your bladder.
