Hi there I'm a sonographer.
One usg to do dating and hear fhr. Best 7-9 weeks
If you have bleeding or crampig or history of MC it could be earlier
One at 11-13 weeks is offered to everyone for generic testing. Its called a first screen. If your over 35 you are AMA and can have a little more detailed testing called panorama. This is elective. You should ask for it if your interested and they didn't mention it.
The there is an anatomy scam when most people find out gender. 18-22 weeks
Then everything else is depending on your age, any issues found, your high risk factors etc.
Hope this helps
Re: Typical ultrasound dates
Yes, I guess I'm being snarky. I apologize in advance of being called on it. Also, I don't understand why you needed to make a new thread for this post. Why not just post it under the "When are your ultrasound appointments?" thread?

My first pregnancy went like this: US at my first appointment to confirm pregnancy, 13 weeks for NT testing, 20 weeks anatomy scan. I was high risk so I had to have one every 4 weeks until 36 weeks and then once a week for NST testing.
My best friend: 13 weeks for NT testing, 20 weeks for anatomy scan. That was it.
This pregnancy, I have one scheduled at 12 weeks for dating because my 8 week appointment was a little uncertain. I'll probably have one a week later for NT testing and then 20 weeks. Assuming I'm not high risk this round, I'll probably go until 36 weeks before my next US.
