If you're pregnant in England you'll be offered an ultrasound scan at around 10 to 14 weeks of pregnancy. This is called the dating scan. It's used to see how far along in your pregnancy you are and check your baby's development.
Your midwife or doctor will book you a dating scan appointment. It will usually take place at your local hospital ultrasound department. Most scans are carried out by sonographers.
The scan may also be part of a screening test for Downs Syndrome/Edwards Syndrome and Patau’s Syndrome. You can read more on these conditions here:
