First trimester screening! I'm freaking out!

Michelle
I am 26 and my SO and I decided to do the first trimester screening since its our first baby. 
Wellllll, we got the dreaded call. We need to go to a specialist because the test is showing possible markers. No other details just possible markers. 
Who all had the test done and had a false positive and it ended up being nothing? I'm freaking out!!!
