Trying to stay positive but how

I just received a phone call from my doctor office today in regards to blood test I had last week. So a medical assistant called and said I had a positive chromosome test come back and I asked her what did that mean she said she didn’t really know and the doctor would like to see me Monday morning to explain more. Like seriously it’s Friday and from where I’m standing Monday is so far away. I know my first part of the downs test came back negative and this was a second part.. sorry for rambling I just wish they could’ve seen me today.
