When Due Dates Dont Match Assuming that the subsequent ultrasound shows the expected fetal growth for the time period between the scans, your doctor may revise your due date to match the first ultrasounds predictions.

Will my due date changed after ultrasound?

Your doctor probably wont change your due date unless its significantly different from your ultrasound date. If you have more ultrasounds, each ultrasound report will contain a new due date based on the most recent measurements.
