Getting an earlier growth scan

Today I had my 28 week midwife appointment. I went in with one question that was a must, thinking that nothing could be done about it, and I'd have to wait.
Last week my consultant told me i'll have a growth scan at 34 weeks. Now to me this seemed quite late, as it was 34 weeks when it was picked up that something was wrong with my son. I explained that if something was wrong, i.e this baby was to have IUGR as well, I didn't want the same mad rush I had at the end of my last.
When I explained why I wanted an earlier growth scan she was straight on the phone to arrange an earlier one for me. So now instead of waiting till I am 34 weeks, I only have to wait till I am 32 weeks. I know 2 weeks might not make much of a difference but I know that if this baby's growth slows it will be picked up earlier.

I think I said a few posts back about last week my bump measuring a week ahead. Well today it's measuring a week behind, which would mean that my bump has shrunk. Looking back at some of my bump photos for this pregnancy the last two weeks don't seem to have any difference to them, if there is it is a very small difference.
