Can the calculation done from an ultrasound report and the one made from your last menstrual period differ as much as 1 week?

Yes, if you have a long cycle they can differ. In my first pregnancy my last period was December 17th which made my due date 23rd September. My ultrasound (at 18 weeks) gave a date of October 4th. I had a 36 day cycle. 3 years later my cycle was 28 days and my ultrasound was spot on. An early ultrasound, around 6-7 weeks is extremely accurate. The later in pregnancy it is done the greater the variation as babies are all different sizes.
