well they say the most accurate time for a due date estimate is 12 weeks. so id go with the 11th.
Due Dates are just estimates. There's really no way to tell what you exact date should have been.
i went though something very similiar with my son....i didnt know i was preg and found out when i was 9 weeks along...or so they think....my original due date was march 10 as time went on i switched obs and when they did my level 2 where you find out the sex they switched my due to march 7
my son was born march 12....they say i was 5 days late with him but maybe i was only 2 days...who knows but i was late
Err stupid phone I meant to say look at nickib
The last comment is reversed. Earlier ultrasounds are more accurate for dating. Its weird that they changed your due date at 20 weeks since usually they wont change it after 13 weeks. Look and kicking she got an ultrasound at like 24 weeks and they jumped her during date up 3 weeks and she ended up being 2+ weeks late. I got an ultrasound at 28 weeks And was measuring 3 weeks behind but they didn't change my date and I ended up having her at almost 39 weeks. I'd say you had him on his due date!
wow, that sounds pretty cool :) only you know that you were given 2 EDD's. as baby gets bigger, due to measurements and height of your uterus etc they have a better indication of how old baby is. Technically you were given a date and baby was born then :) x
My actual due date is 40 weeks and 2 days! lol
How annoying is that??

Forgot to mention that he estimated that i concieved between August 9-11th.. so that makes me feel like the 11th was more right.
