Hi! If you were my patient I would advise you that how accurate your due date is depends upon how it was determined. In other words if you due date is based upon a first trimester ultrasound it should be accurate within 5-7 days and that would make your conception date likely to fall between the 16-20th of June. It could still be off by as much as a week making the 26th possible. IF your due date is based upon your LMP it is likely to be LESS accurate and the 26th certainly could be a possibility. My calculation shows: LMP June 5 == EDD March 14th and conception date June 18th-19th. Because of the 7 day margin of error I would think that the 26th is a possibility. Good luck!
