Well, I went for mine, and it said i was 6weeks 1 day (=- 2 days) but it was a really blurry look, and the measurement was done roughly, so the doctor has stuck to the original dates we have from FF. I saw a 3mm bub, with a hb of 101bpm.
I was meant to pay $90 for the scan, but as I was referred by the AMS (which is a clinic in town mainly for the aboriginal community, but also serves 20-30% of white folk, like me. ) so I was bulk billed for it, and dont have to pay for my 12 week scan either So I am not complaining hehe
