I guess the first appointment with the GP depends on when you discover you're pregnant. I wanted 'shared care' between my GP & the midwives/OB at my local public hospital so I requested a referral from my GP at my first proper appointment. Alternatively, if you're choosing to have private cover or your own OB, I believe you can start calling around to find out about availabilities. All of this is ideally done as early in pg as you can....from what I've heard, any available spaces fill up VERY quickly.

The number of Ultrasounds depends on your pregnancy and your GP. I found from my local hospital that they pretty much only do the 18-22wk morphology scan now. Of course, if you have unexplained bleeding or cramping, they will generally send you for an U/S to check everything is ok.
