Level 2 Ultrasound

Kayla
Just got a call from my OB saying my quad screen blood tests came back ok, but the Down syndrome one I was at slightly higher risk. I guess the ''norm" is 1/150 and mine came back 1/130. So they want me to go to the hospital and have a level 2 ultrasound done to double check everything and more in depth. This is my first pregnancy, it's all new! My anxiety is through the roof right now. Anybody had a similar experience? What do they do at a level 2 ultrasound?? Thanks in advance!
