Measurements: Your first due date was likely based on your last period or some very early ultrasound measurements. Both are fairly inaccurate. As you progressed, your due date was refined based on later measurements. Remember, though, doctors (like anyone) are not great at predicting the future. Only about 5% of babies are born on their due date. Hope this helps!
