Anatomy scan.. help!?

Goodmorning ladies! I am 16 weeks and 3 days pregnant! I had a prenatal check up last week and my doctor gave me a referral for a anatomy scan! I couldn't wait until the 18 week mark so I went ahead an made the appointment for today! I was wondering if any of you ladies had a 16 week anatomy scan an you found out the gender?? I'm so nervous and excited ! What should I expect , thank you for your feed back😊
