Answer: Hi dear
The Edd on first sonography will be based on ir last lmp.Edd given on later sonography was based on the fetal size and growth.Ofcourse The delivery will not happen on the exact date that was givenfor most women.It shows only the expected date .It may during the next sonography as the position and size and growth of ur baby changes.delivery may be expected +or - 10 days by the given date.
