The dating scan is generally the first ultrasound that every mother-to-be will have.

A recent article explained that doctors are now going to be using first trimester ultrasounds to determine due date in the majority of pregnancies.

Earlier this week the American College of Obstetricians and Gynecologists (ACOG) met with the American Institute of Ultrasound in Medicine and the Society for Maternal-Fetal Medicine to set new guidelines for due date determination. James Goldberg, vice chair of ACOG’s committee on obstetric practice, stated, “Some studies suggest up to 40 percent of pregnancies would have dates changed based on [a] first trimester ultrasound.” This difference is because most women do not know the day they conceive and the 40 week rule-of-thumb is based on a 28 day cycle, which is not always a good guideline for women with irregular or longer cycles.

Using ultrasounds to figure out a due date really made the question “when are you due? Unfortunately for women who do know when they last had a period, this technology may muddy the due-date waters. She was one of the conflicted women who had a due date change because of a first trimester ultrasound. Was she due on the 5th (based on her last period) or was she due on the 15th (based on the ultrasound)?

She ended up having her baby the 14th, so it looks like technology won the battle in this case.
