Dont worry, mine were a bit like that, some things were measuring ok for dates, some slightly bigger etc. This is perfectly normal, if they were outside normal ranges it would have been discussed with you
I can't remember the actual figures for ds (it was 2 years ago) but I do remember laughing (nervously) with dh that he had really long arms, and a huge head, everything else was on the 50th centile. I thought we were going to have a gorilla!
He looked nothing like a gorilla at birth (though he did have a big head) and is perfectly in proportion now.
