Changed due date

Erica

I need opinions.. Originally I went to an OB appointment when I thought I was about 8 weeks according to LMP and my ultrasound read 6w 6d and we had been going of that date making my due date the 28th of December. I ended up like liking the doctor and office so we switched to another and went in when according to the first doctor I would be 14w 2d. The new OB wanted to do an ultrasound just to see and based on the new measurements he has changed my due date to January 7th which put me at 12w 2d. Now I am just confused, I have heard people say that I should stuck to my original due date because measurements are more accurate in the beginning and baby will grow at their on pace from there. What do you guys think?
