An early pregnancy scan is available from 6 weeks — though there's often a good reason to wait a little longer.
We offer early scans from 6 to 17 weeks, and we often recommend leaving it until after 7 weeks where possible, because at that stage we can normally get more accurate information.
The scan checks for a fetal heart, looks for multiples, checks where the pregnancy is located, and calculates gestational age and your estimated date of delivery.
A full bladder is needed. In very early pregnancy it is often necessary to perform a transvaginal scan, which gives a much clearer and enhanced view — your sonographer will explain and ask your permission before proceeding.
Sometimes it is simply too early to confirm whether a pregnancy is ongoing. If that happens we will recommend rescanning in 7–10 days rather than drawing a conclusion on the day.
No referral is required for pregnancy scans, and we are open to all patients — not only those attending the National Maternity Hospital.
