When LMP and Ultrasound Dates Don’t Match: When to Redate?

When LMP and Ultrasound Dates Don’t Match: When to Redate?

The first trimester can be an exciting but anxious time. Expectant parents often need to wait for up to 15 weeks before they get their public maternity hospital appointment and the reassurance that everything is fine with their baby. With our private ultrasound scans, you can get this reassurance as soon as 8 weeks gestation so you can begin to enjoy your pregnancy with peace of mind. Pregnancy Scans performed during the first 12 weeks of pregnancy are generally within 3 — 5 days of accuracy. The most accurate time for the due date calculation is between 8 and 11 weeks pregnant. This is because your baby is growing so quickly that there is a big difference in size from week to week. Also, the baby cannot bend and twist very much yet, so the length of the body is fairly constant. However, the accuracy of the ultrasound examination is always dependent on the position of organs and internal bodily fluids. Sound waves are produced by the equipment, then the software translates these sound waves into an image. We can get a 2-dimensional picture of the baby at this stage.

Pregnancy math can be a little murky. After all, unless you went the IVF route, your physician has no way of knowing the exact time of conception. Because of this, pregnancy is calculated from the first day of your last menstrual period or LMP. From that day, weeks of pregnancy is officially counted, and your doc or midwife busts out the red pen and marks your due date on the calendar. Sometimes, however, the due date may be revised. It can be pretty difficult to determine a due date using the date-of-last-period method for women with irregular cycles — which is why an ultrasound exam is often required to determine gestational age.

An early ultrasound, usually done at about 6 to 9 weeks, can give the most accurate due date estimation by measuring the size of the embryo or fetus.
