First appointment with my ob at 12 weeks?

I went in and met with a nurse to get the pregnancy confirmed. We were pregnant :) and she made my first on appointment for 12 weeks. Is this normal? I am 9 weeks tomorrow and I feel like everyone I talk to has had an 8 or 9 week ultrasound appointment. First baby, no problems, very sick the first 4 weeks now its every few days and very sorry breasts...
