Ultrasound scanning is dependant on many different variables, it depends on the machine being used, whether it was abdominal or a vaginal scan and of course on who preformed the scan.

In the majority of cases the earlier the scan the more accurate. Was a fetal heart pulsation visible?

The gestation of the fetus can vary depending on your history, do you have a regular menstrual cycle, ie. between 28 and 30 days from the first day of one cycle to the first day of the next, if outside of this then your dates will vary as Naegels rule of pregnancy doesn't apply because you ovulate 14 days before your period starts. Were your last three periods of normal length for you? Were you on the Oral contraceptive/any other contraceptive or pregnant/ breast feeding or have any other event or medication that could have altered your body's hormonal response three months before you conceived?

If any of the above then using the 1st day of your last menstrual period won't be accurate.

Now unfortunately there are other reasons also, but the above has to be ascertained first.
