In Australia it is 12weeks and 20weeks... then only if required to check growth (if they think to small or big or another complication.)
Thats public.
You get more in private.
This is a question for your doctor for all of them are different when it comes to this.
I had an ultrasound at 20 weeks hotel me the gender, and one at 36 weeks because I asked my doctor to give me an estimated weight at 32 weeks and he was 6 pounds.. That was my first pregnancy this time around I got a ultrasound at 9 weeks and due to some Heath issues I'm getting another at 11 weeks.
