Whats My Due Date?

[savvy1696]

My first due date was given to me at the emergency room, they claimed I was 3 weeks and 5 days - ( Due Date March 28th, 2014 )

THAN I went to my first obgyn appointment and they went along with that due date, just because they needed to give me some sort of understanding about pregnancy. BUT once I got my first ultrasound ( tons of weeks later ) they told me I wasn't 19 weeks, I was actually 20 and changed my due date. ( NEW due date - March 20th, 2014 )

I'm just trying to get an understanding on why they changed it, if my first due date was ever actually true AND which one I should go with?  

..I mean, the emergency room does get alot of people, and they could get lazy!

I'd go with ultrasound one, because it actually measures the baby and everything

The ultra sound is the one that would be the most acurate. Honestly it's only a week so it won't make a big diference. Most doctors let you go until 42 weeks before inducing you if you don't go into labor on your own. Either way bubs will be fine. Just use the due date from the ultra sound because again, that's the most accurate one. Expecially if it was a vaginal ultra sound.
