My GP did all the right tests but didn't give me a lot of advice. I found out I was pregnant at 8 weeks.

She did give me a HCG levels test, so I would ask for that this time. I did the HCG, then went back and got an ultrasound at 9 weeks, and the screening blood tests etc you are referring to. She then sent off for the hospital referral, but the RBWH have you do the 12 week blood test, and NT ultrasound, and the 20 week ultrasound with referrals from the GP.
