Will you get the cell free-DNA testing?

My doctor offered it to me and I’ve been considering it, but I’m also terrified of the results and that they might make me dread the rest of my pregnancy. I know that sounds horrible, and i really don’t mean for it to. I’m just a worrier. I have one uncle with down syndrome and as far as I know he’s the only one in the family. My sister did not have this done during her pregnancy. I was just curious as to how many people actually get it done and if maybe talking to my doctor about what my risks are could help me decide.
