Women have cycles that are not all the same length but most women ovulate 14 days before a period is due. That is what makes the difference. At 7 weeks ultrasounds are accurate to within 3 days. At 20 weeks they are accurate within 5 days When I had my first pregnancy my cycle was 36 days which would mean my EDD would be 8 days early if my LMP was used, my US agreed with my cycle not my LMP. When I had my second pregnancy my cycle was 28 days and my ultrasound agreed with my LMP. So you are saying that the ultrasound is more accurate? Yes, the ultrasound is more accurate. I did go round the houses a bit to say it.
