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.

An image of the fetus appears on an accompanying computer screen. While looking at this image, the technician takes some standard measurements from different angles and listens for a heartbeat. Sonograms are risk-free, and seeing your baby will likely be an enjoyable experience. Naturally, one of the most common questions asked about ultrasound is: Just how accurate are due dates predicted by ultrasound?
