Throughout my pregnancy , I’ve received two different due dates — one came from my very first ultrasound, when my baby was barely the size of a blueberry, the date that was then subsequently stamped on my record as “the” due date. But then there was a second date, the one that showed up on my next couple of ultrasound scans. This date was a few days earlier. It’s also the date that I prefer, not only because I’m now 38 weeks pregnant and ready to get this baby out, but because it matched the date I’d calculated on my own using information I looked up.

Traditionally, estimated due dates are calculated by taking the start date of a woman’s last menstrual period and adding a year, subtracting three months and adding seven days, a method known as Naegele’s rule. But that method doesn’t account for irregularities in a woman’s menstrual cycle — if she has a longer or shorter cycle than 28 days or any variability with ovulation, for example.

The most accurate way to date a pregnancy is with an ultrasound done between 6 weeks and 8 weeks, 6 days, according to Dr. As a woman’s pregnancy progresses, fetuses develop at different rates, which is why an estimated due date from an ultrasound measurement during the second trimester is less accurate.
And why I probably shouldn’t be taking my second “due date” very seriously. As much as technology has improved, this is all still an imperfect science. Once you go past about five or six days, then you have to start considering that your dates really may be off.
