I'm sorry to hear that you've got a bump in the road.
In my case they diagnosed IUGR at 37 weeks so they induced.
They were fairly certain baby was under 5 lbs.
They were off by more than a pound which in baby land is a lot.
Post delivery conclusion was I did not have it.
Just inexact measurements.
So DS was fine, no NICU time and gained a lot his first month.
(A pound his first 7-10 days). Has had steady growth since birth.
Fast forward two years he's average size and very smart for his age (more like a four year old than a two year old).
They do err on the cautious side with IUGR and will strongly recommend delivery. They gave me the pros and cons (and the cons of waiting were frightening) so it was an easy decision for us. Packed up and went right over.
The peri had been using the doppler to track blood flow on both sides in my final trimester and I did have ongoing stress tests which had been fine.
And I was scared to death between the IUGR call and the birth a few days later.
I know a few others on the board had definitely did have IUGR, a couple in twin situations so hopefully they'll post. In the two cases that come to mind, their kids (I believe 4 and 1) are perfect ine very way.
But hang tough and know regardless you're at a good weight.
Keep us posted and hope this helps.
