I think this is within the normal range and wouldn't be concerned particularly if everything is looking perfect. Babies don't all grow at the same rate, and there is some margin for error in the measurements made during ultrasounds.
Hi Ashie, At my 12wk scan bub measured 3 days behind, then at 18wks she was measured 11 days behind, they were both done by the same lady. When I saw my Doctor at 21wks she wanted a 2nd opinion and so I went to a specialist ultrasound place and they measured bubs at only 3 days behind. They said it could have been bubs position when the measurements were taken and the lady doing the ultrasound been a couple of mm out and that can make the big difference. I will have to wait a few more weeks to let you know how big she is but she does not feel tiny to me.
Sounds like your OB is going to keep an eye on you so I would not worry to much. Goodluck with the rest of your pregnancy.
When I was pregnant with Tristan they added 12 days to my LMP due date.... at every single u/s he had caught up more to what would have been my gestation based on LMP, he was born at 34+3 weeks and 3.09kg, the average 36-37 weeker.
U/S are not 100% spot on and can be out. Also as someone else pointed out not all babies grow at the same rate.
It's great they will be monitoring you a bit more, hopefully just as a precaution and nothing else.
thanks girls, it came as such a shock to see him falling behind in dates cause i know mine are pretty spot on, he was being a little wiggle bum and not wanting to help her get the measurements, and kept changing into harder positions. i see my ob today, so fingers crossed his scan he does shows some growth or a mistake. i havent put much weight on either started out at 45kg only just at 48kg with the other boys i piled on over 20kg with each one! but we are still happy even if he is little, never had a little bub before lol.
