Dating scans in pregnancy

Early in pregnancy there maybe few signs to suggest that you are pregnant.

You may have had the ‘blue line’ which suggests you are, but to see for sure will give you added reassurance.

There are two routine scans in pregnancy and the first is called the 12-week scan or “dating” scan – this is because one of the things it looks at is the exact gestation, giving a better idea of your baby's estimated due date.

The dating scan is usually done at some point between 8 weeks and 14 weeks pregnant.

The dating scan is an ultrasound scan that can be done as early as six weeks after the last period, but the dating scan will be most accurate when done between 8 and 12 weeks gestation.

At this time, the fetus is a little larger and easier to measure.

Even dating scans can be inaccurate for the due date, but they are never as inaccurate as using the menstrual period.

This scan can be carried out from 6 weeks to 18 weeks.

The most accurate time to date you pregnancy is after 8 weeks through to 13 weeks.
