"Advanced" due date calculator?

[miranda90]

Has anyone heard of this method, "mittendorf williams"? This site provides a due date calculator; https://www.yourduedate.com/?advanced and I do get a different date (3 days earlier!). I'm wondering if anyone knows anything about this method and if it indeed more accurate?

thanks!

It gave me the same due date as my scan said

It doesn't adjust for cycle length so it's off on conception/ovulation date for me

Pretty sure it's the same one I posted last time I was pregnant!!! I think it's neat

It's not the same! I found the one I found last pregnancy though lol I posted it.

That one had my EDD 5 days earlier (the 5th instead of the 10th). My ovulation date was off by 2 days. But, I guess it doesn't matter because I know this baby will be born any day but the 10th lol

Lol!

This one put me at Aug 2.
My own look-up put me at Aug 1.
My cnm said it was Aug 3.
And my u/s tech said July 28.

This one puts me at October 8th. LMP puts me at October 10th
