How accurate is a dating scan?

How accurate are dating scans? A dating scan is the most accurate way to predict your due date, also known as your estimated date of delivery (EDD). The point of the scan is to work out how many weeks pregnant you are. You may have calculated the length of your pregnancy from the first day of your last menstrual period (LMP).

Can you do a dating scan at 8 weeks?

The first dating scan is usually done after 10 weeks, and this is the norm all over the world. This doesn’t mean that you cant do a dating scan at 8 weeks either.

A scan date is normally spot on although if theres a few days difference between the scan date and your date they will go with your dates.

Youll only have a scan before this, between six weeks and 10 weeks, if youve experienced bleeding, pain, or problems in a previous pregnancy (Miscarriage Association nd).

Are dating scans more accurate than LMP?

(I already have twins) ps Congratulations! i meant to add: dating scans are more accurate than LMP, as you can ovulate any time in cycle...

When is the best time to have a scan?

If you’re unsure of your dates, we can still offer you a scan; we will book you in from 2 weeks after your first positive pregnancy test. This ensures you’re at least 6 weeks. If you’re feeling very anxious, we would recommend trying to wait until nearer the 7 week mark. This is just incase there’s a slight discrepancy with your dates.
