Pregnancy ultrasound scans work better if you come with a full bladder for the dating scan, because it estimates when your baby is due (the estimated date of.

That baby is due in a week — you feel as big as the Death Star, you have to pee 7 million times a night and you just want that baby out! But should you keep going to work as usual, or fumble through the car seat installation instructions and get that birth bag ready? Ultrasound measurements of the cervix, the passageway at the entrance to the uterus that opens up to make way for a baby during delivery, can reveal whether labor is likely within the next week, according to a new study.

The method is safe, and women already get frequent ultrasound scans during pregnancy , said study co-author Dr. Though most women are given an official due date, it is often just a rough estimate. Only 5 percent of women deliver on their due date, according to American Academy of Pediatrics. A healthy pregnancy is, on average, 40 weeks from the last menstrual period, but in reality, most babies come sometime between 37 and 42 weeks gestation. For many women, that five-week window creates a waiting game that can feel unbearable.

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.

And how much does it really matter? After all, as many moms know, due dates are just educated guesses. 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.

That’s why the American College of Obstetricians and Gynecologists recommends doctors use ultrasound measurement in the first trimester to establish an estimated due date. The most accurate way to date a pregnancy is with an ultrasound done between 6 weeks and 8 weeks, 6 days, according to Dr.
