Question: Can ultrasound scan dates be wrong?

3 Early ultrasound due dates have a margin of error of roughly 1.2 weeks. After 20 weeks of pregnancy, your estimated due date shouldnt change based on an ultrasound because it will be less accurate. And remember: Its an estimated due date; the vast majority of women dont deliver their babies the day theyre due.

How often can an ultrasound be wrong?

The chances of an error with ultrasound are up to 5 percent, says Schaffir. An ultrasound can be between 95 to 99 percent accurate in determining sex, depending on when its done, how skilled the sonographer is and whether baby is in a position that shows the area between their legs. Mistakes can also be made.

Is it possible to miss a twin on ultrasound?

Its not unheard of for a twin pregnancy to go undetected in early ultrasounds (say, around 10 weeks). But once you reach the midway point of your pregnancy and have your 20-week anatomy scan, you can be 99.99 percent confident about how many babies to expect at your delivery.
