I found with DD my OB appts were always atleast an hour wait past my appt time the most i waited was 2hrs15min.
The midwives clinics were also very busy and was nothing to wait over an hour each time.

This time round they have put me at their Panch clinic as the Mercy clinic is FULL yep thats right no room at the midwives appts AT ALL for me on the day i go.
BUT in saying that it works perfectly as i take DD with me and there we only wait 15min for the midwife... YAY
I had an appt with the OB and made it as early as possible and only waited about 30min.

It is hard with public and at the moment we must be going through another baby boom, just my luck as with DD there were 23 births in my hosp the day she was born!

GL with it all and i hope you don't have to wait that long all the time.
