Mel, there's not much more than five days between the dates which isn't a lot when you think about it. Maybe you can tell people it's the later date so you don't get driven mad by phone calls when bub doesn't arrive on the earlier date =)

I'm one of those lucky ones (like Sush) who because of IVF know exactly the date on which the baby was conceived. At every ultrasound he has been spot on for dates according to the initial calculations. However, it's his due date today and he still isn't here for reasons probably known only to himself =) I guess this is an example of them having their own timetable, in spite of every calculation being correct.
