How accurate are ultrasounds for dating pregnancy what's the margin of error. if my due date is oct 31, what are the dates i could have gotten pregnant?

What year?: It would seem that you would have to conceive on feb.. 8, 2014 to give birth on 10/31. If the question is of historical interest, i would need to know when the ultrasound was done. Otherwise, you might want to check the dates you provided.
