Yesterday at my apt my stomach measurement was measuring 5 weeks ahead (and has been measuring ahead every apt since I was 18 weeks but only by 2 or 3 weeks) so my doc had me come in today for a growth ultrasound and see how big our little guy is. The ultrasound says hes measuring 4 weeks ahead..
With my first DS he never measured ahead or behind and wasn't a big baby so I'm confused as to why this is happening?
Do you think I miss calculated my dates? I did have an ultrasound at 12 weeks though so that doesn't seem likely to me? Or maybe its just a bigger baby? Even though my son wasn't big? Do you think he'll change my due date?
Thanks for your input. Just a little curious as to why I'm measuring so far ahead!
Re: Measuring ahead.. 5 weeks ahead!
From what I have heard, the earlier the ultrasound, the more accurate it is. Even dating by ovulation/periods isn't as accurate (to my understanding).
When I first met my OB and we talked about "due dates", she said that once it is established - usually by means of a dating ultrasound (the most accurate), she won't change it unless it is substantial. To her, substantial is - 1 week in 1st trimester, 2 weeks in second tri and 3 weeks in 3rd trimester. Meaning, in your situation, since baby is measuring 4 weeks ahead, I would think my OB would move my date up.
All of that being said - not sure how accurate ultrasounds are at this stage in the game. So your doc may or may not do anything depending on what he determines. It would be unhealthy for baby to think he is due earlier and induce for "going over" instead of just letting nature run it's course and let him come when his time is right.
This is why due dates SUCK!

Thanks for your input! Due dates DO suck!! I had the ultrasound today but don't meet with my doc for 2 weeks so I'm very anxious to see what he has to say.
THANKS again!
