A dating ultrasound or dating scan is a scan done early in pregnancy (before 12 weeks). It is usually done to check how many weeks pregnant you are and therefore to calculate the estimated due date, but it can be done for other reasons. Only a few women need a dating scan.

Is dating ultrasound necessary?

A dating scan might be recommended before 12 weeks to confirm your due date if you are unsure of your last menstrual period or your date of conception. The scan is optional and not everyone will have it. You can discuss whether you want or need a dating scan with your doctor or midwife.

The first routine scan is offered at around weeks 11 to 14 of your pregnancy. The timing of scans can be a bit different depending on where you live and when you first see your doctor or midwife. Seeing your baby for the first time can feel like an exciting event. You may feel anxious too.
