What happens at first prenatal appointment?

Ne

A couple of days ago I found out that I’m pregnant and have my first appointment the day before Christmas. They mentioned doing an ultrasound and then something about a physical exam? But I think they said that was going to happen at another appt? I was nervous and excited and the receptionist wasn’t the nicest so I feel like I missed some things. She also didn’t tell me if I needed to have a full bladder or not. Obviously I will call them again to confirm when we get closer to the date to ask my questions but I just wanted to hear from those that have done this before. This is my first pregnancy.
