Pregnant dating scan accuracy

Ask your GP if you want the reassurance of an early scan. The scan's main purpose is to work out accurately how many weeks pregnant you are and estimate your due date.

You may have calculated the length of your pregnancy from the first day of your last menstrual period (LMP).

Your Facebook name, profile photo and other personal information you make public on Facebook (e.g., school, work, current city, age) will appear with your comment.

Having a scan in the first few months of pregnancy can be a thrilling experience.

The computer in the ultrasound (ignorantly) lumps your bigger baby into the dates of babies that big in the “normal” population.

This may then indicate that your 37-week baby is two weeks overdue!

Although the dating of pregnancy accuracy takes a dive, still ultrasound is indispensable for the other uses.

This is even though you don't actually conceive until 14 days after your LMP, or later than this if your cycle is longer than 28 days.

You probably know when your LMP was, but not when you actually conceived.

The software has certain measurement scales based on data from large populations, and your baby’s measurements are put into this scale.

In other words, by comparing your baby’s measurements to the data from this large collection of measurements, the ultrasound can then tell how far along your baby is.

Even when the last period is known, ultrasound is reassuring to demonstrate adequate growth, especially when there’s a risk of delayed growth, as in hypertension or smoking, or if there’s the risk of exaggerated growth, as in gestational diabetes.
