Quoting Queenbee021408:" Has anyone had an ultrasound done and their due-date was pushed a little over a week back but it was ... [snip!] ... sure I am really a week behind, or my first due date that was given is correct but it's driving me insane thinking about it!"
I know alot of drs wont push you back if youre a week past your LMP. I know for a FACT i ovulated late and Im not due til the 22nd (positive OPKs and Im measuring a week behind) but my dr refuses to push me backward. Its rare to have a baby that small be miss calculated BUT anything could be possible. he/she could catch up by your next sono or baby could just work better for the tech. either way, congrats!
