when is the earliest you can have a dating scan?

[DANNIIM]

I had one at 8wks....still looked like a little alien, but was so good to see what he/she looked like already!
I've had 4 scans in total and it is just glorious to see how much he/she has grown since the last one
8wks dating scan
12wks nuchal screening
19wks morphology screening
30wks growth assesment

Not long now!

Preg - I'd go 8wks for a couple of reasons. If you are not as far along as you think then at least you'll still be around 7 wks and they can see clearly at that stage. My doctor recommends 8wks because it is a good time for accurate dating. Going any earlier can be disappointing if they can't see much.

i had one at 6 weeks and they could not see anything but a sac, so of course i freaked and thought straight away 'blighted ovum again" ....but all is fine!!!! i wouldnt go before 7 weeks just to be sure that there is something to see.
