Well the most they'd do at a GP appointment to confirm the pregnancy is a test, usually a pee test and sometimes they'll send you for a blood test. They won't be looking at any down there bits, unless you're due for a pap smear I think? GPs generally don't do ultrasounds either.

If you don't really feel you need to see your GP, you can contact the hospital you are going to use, or if you're going private then you can start contating Obs (do it early as they book out apparently), and see if you need a referral and then just take it from there.

Generally the hospital and Obs wont see you until you're 12 weeks though, so keep that in mind if you want the 12 week scan as you may just nneed to go to the GP for a referral as usually you have to book a few weeks earlier for the scan depending on where you live.
