I got an appointment that far in advance from the womens - it was described as a scan because of 'advanced maternal age'.....thanks

But I also got a seperate letter stating that all other blood tests and scans should be organised through my doctor.....so I ended up getting a 6wk (through the fertility specialist), the 12 and 20wk scans through a referral from my GP (had to pay for these).
I don't think any of the hospitals do a 6-8wks scan as routine....most people get these as a dating scan just to confirm dates (but more cause they want to make sure bubs is OK).

With my first I was asked if I wanted to do a 12wk scan and that was the first scan I had.
