    yep def dont worry about it. i remember being told the later in the preg the more room for 'error' - ie may measure above or below and a week either side would def be right. My OB said til about 12 wks it is more developmental (even better earlier) and so easier to measure for dates and after that the later you go the more genetics have to play a part (same with diff body parts measuring diff ages ie my DS had legs that measured about a week 'older' than the rest - he must have just had long legs - as i do - not that you could tell when he was born or now)

    Yep - Bub was measuring 8 days ahead when we had our 20wk scan. I know my dates are spot on as I was on Clomid and charting my temp. My Ob even based his dates on my chart rather than LMP. My fundal height has been around 2cm ahead too but OB is happy as he said it means Bub is obviously well nourished. He prefers Bub's to be a little bigger than anything else. I think I am just going to have a big Bub as I was a big Bub myself (10lb 3oz).

    Personally, I'd keep your dates as they are. This way if you go 'overdue' they won't jump up and down as early and try to induce you.

    that sounds good, thanks. i'll just count it as it is, like you said a bit better to be a week ahead than behind. my ob only got the due date from the date of my last period cause i never had a earlier dating scan cause i was so sick, but thats what i was thinking, i'm sure he/she let me know when it's ready. ha ha.

    I have ALWAYS measuread *ahead* up to 2 weeks.

    I had last scan at 19w5d, measured 21w and the Ob very sensibly said - the world is made up of people of all different shapes and sizes. Not going to change EDD, if you go early that's a bonus!

    Um, and I did go 10 days early - so nice to not have to wait till that dreaded date ..

    At my last scan at 28 weeks they measured bumps head, abdo and leg and she said he is a big baby. Measuring about 2 weeks ahead of himself. Its kind of good to know he is growing well but at the same time I am scared now that he will come early. He has been engaged since 27 weeks and has dropped quiet low as his head presses on a nerve that shoots down my woohoo. My tummy has dropped heaps also.
    I am only little 5ft1 and DH is 6ft2 so I am scared that bump will be too big to pass through my pelvis. Will tell obs next week that this is making me panic a bit. Need some reassurance thats all.

    The other thing I said was that God (or mother nature etc) will give you the perfect baby for your body... no bigger, no smaller. Remember He only gives us things he knows we are strong enough to handle
