A member asked:

If my edd is february the 17th 2022 when did i conceive roughly? 7 week scan was 9.5mm and 12 week scan 53.0mm is this pretty accurate with dates?

A doctor has provided 1 answer

Based on a pregnancy calculator, the first day of your last menstrual period was May 13th. If that is correct, the most likely date of conception was about 2 weeks later, around May 27th. The 12-16 week scan is generally considered to be more accurate for due dates than the EDD based on your LMP. Best wishes for a healthy baby
