Wonderful news! I am so sorry to hear of your other losses but so happy to hear your good news! There are numerous reasons why you could have looked so behind. First, there is always human error and if a tech is rushed, that is definitely a possibility. Also, if a woman's uterus is tilted, this happens quite a bit. When the uterus is in a more normal position later in pregnancy, dates even out. Maybe your uterus just moved a bit.
Whatever the reason (and I do believe miracles happen!), CONGRATULATIONS!!! I do hope you update occasionally.
