Nuchal fold .19 and referred to a specialist

I am 10weeks 5 days and finally this pregnancy was normal. Today we went for our first appointment with a doctor and I was referred to a specialist for the thickness of the nuchal fold and possible diagnosis of Down syndrome. To say I’m freaking out is an understatement. My husband also got his orders today to deploy for a year. Has anyone ever had this? Any advice will help!?
