First ultrasound?

I am a first time mom, and have no idea what to expect with doctors appointments. How early did your doctor do your first ultrasound? I'm only 5 weeks 2 days along, and have an appointment on the 21st (it was already set for a wellness check before I found out I was pregnant😊). I am dying to have my first ultrasound!
