repeat anatomy scan.. freaking out

Kendall
I went for my anatomy scan at 20w6d. I received a call that they need me to come back as soon as possible. I need to have a consultation with a doctor and more images taken. I didn't meet with a doctor before or after my first scan. Naturally, I'm freaking out. I did ask the tech if she saw any soft markers for downs and they said no...has anyone had this and everything was ok?
