I've just kept the same due date of my first ultrasound. Although a few after he measured 2-4 days earlier
They told me 27th then 22nd but I'm measuring a lot further along so I'm going with 22nd
Usually you go by the date of your last period for your estimated due date but each ultrasound may vary 5-7 days before they actually change your first estimated due date. My due date was February 22,2015 and I had my son the 20th but each ultrasound was different... One was the 22, one was the 23 and one was the 25!
I'm not sure when I'm due. I have three due dates august 13th, 15th, and 17th. Baby will get here when baby gets ready.
Well your due date is estimated... Some people go over their due date and sometimes the babies size varies by a few days!
