Dating scan?

Amanda • 22. Married 💍. 3 year old son. Due with baby #2 July 5th 2016.
I live in Georgia & have united healthcare. I had my first appointment and they did an ultrasound to confirm pregnancy. No blood work or anything else. We go back December 18th for our next appointment. I'll be close to 13 weeks. Is this when they will do a dating scan?
