Congratulations!!!!!
I had mine about 10wks ago and it was 1.5hrs plus the wait. I am with the FMU midwife so the wait is a little different. But when I had to see the antenatal nurse the other day she was running about 45mins late. She was very apologetic though, which is nice as some people don't care that they keep you waiting!
The best thing that happened in my appt was they booked ALL my appt's for the rest of the preganacy then it is great for planning as I have 2 other kids, one with a lot of appts herself!
The other thing I would let you know is to get there early as parking is at a premium close to the clinic. We have a mobility sticker and it still takes us ages to find a park. You can walk from the multi-story carpark but you will walk the entire length of the hospital - not ideal when you get to 30+wks preg!
Am loving the public system though I am a convert as I went private with my first two and am now kicking myself for the waste of all that money
