Can you please help me to code this ob encounter?

Scenario:
An established patient visited the clinic for her initial antenatal care. She is currently 15 weeks pregnant (G2,P1) with previous cesarean section due to breech presentation. This is a spontaneous pregnancy. Patient has currently no complaints. No nausea, no vomiting, no abdominal pain, no vaginal bleeding. She is a known case of Uterine Fibroid, and Iron Deficiency Anemia. Patient is taking oral iron replacement. No surgical history, negative family history. The physician requested dating scan and booking investigation for the patient.

I hope you can help me with this.

Thank you!!!
