NHS and private ultrasound scans during pregnancy

The first trimester can be an exciting but anxious time. Expectant parents often need to wait for up to 15 weeks before they get their public maternity hospital appointment and the reassurance that everything is fine with their baby. With our private ultrasound scans, you can get this reassurance as soon as 8 weeks gestation so you can begin to enjoy your pregnancy with peace of mind. Pregnancy Scans performed during the first 12 weeks of pregnancy are generally within 3 — 5 days of accuracy. The most accurate time for the due date calculation is between 8 and 11 weeks pregnant. This is because your baby is growing so quickly that there is a big difference in size from week to week.
