Ultra sound results - can anyone explain the soft markers they noted?

R

My ultra sound results came in today and I am freaking out. I have a follow up doctors appointment on Friday and will get clarification then but does anyone have experience with these showing up and going on to have a healthy baby?

I had genetic testing done in my first trimester and nothing came back as a red flag, they said everything was looking good. I have one other daughter and no genetic issues and none run in our family on either side.
