When they do the dating scan varies, some get it early if theres any complications/previous problems but a standard pregnancy has it around 12w, some also have the NT scan at the same time then.
My dating scan was literally measure the bubs then look on a graph. They did a few more measurements probably to check for seriously obvious abnormalities, but it was pretty basic just because theres not much to see at 8w.
Shattered from work today, felt like there was NO air in the room all day. Lunch was provided as it was a training course, but it was all sliced meat sandwiches which I dont trust now. Have no way of knowing where they got it from. Ended up eating carrot sticks and a banana, starving!
Ordered DH a mug with 12w scan pic on and it arrived today, its so cwute!
