Possibly.: There are many ways to date pregnancy. Sometimes the last menstrual period is the most accurate method and other times ultrasound is the most accurate method. Your doctor may have simply dated your pregnancy from something other than your last menstrual period. If you still have questions just ask your doctor to clarify.
