Lordy me, a subject close to my heart With DD1 my EDD were June 1st and June 3rd according to scans. She arrived with assistance on the 17th. With DD2 my EDD were October 28th and October 15th, she arrived on November 9th.

Personally, I think the emphasis put on EDD is silly. Really, like Kelly said its based completely on speculation unless you know how many days are in your cycle & the ovulation date & the exact date of implantation....

I would always take the later EDD. That gives you more time to play. With my DD2 I told everyone my EDD was sometime in early November knowing that she wouldn't be early....HTH!
