First Ultrasound!

Melissa
I'm 7wks2days tomorrow and have my first ultrasound! Can anyone tell me what to expect at this appointment? I went to my midwife at 5 weeks and they confirmed the pregnancy. 
I have only been nauseous once or twice. I feel tired all of the time and my breasts are sore constantly.  Is this normal? I thought for sure I'd have more morning sickness. 
 Im naturally not a fan or doctors/appointments do anything to alleviate my anxiety would be super helpful. 😊
