Yeh, I'm pretty sure too that if you don't have any significant history (eg.. previous MC or gynae problems or problems with the pregnancy) then they won't do an US to late in the first trim. But I guess it depends on the obs/ or GP..

With my first pregnancy they were just going to do the first US at 12 weeks when they do the check for downs..which seems sooo long before you even get to see your bubby for the first time..(but I had some bleeding early so they did an US very early)..
My friend is just pregnant too, and has never been preg before (so no history of problems) and she booked in with an obst. and they said to come in at 9 weeks when they do there first scans...
So probably does depend on who you see a bit..
