Youll have a dating scan appointment, also known as a 12-week scan, between about 10 weeks and 14 weeks of pregnancy. This is usually the first scan youll have, so its likely to be a significant moment for you.

Is 12 week scan 12 weeks from last period?

Why would I have a dating scan? 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.
