word file that I saved and I can not find

Hi!

So I was working on a word file for several days and saving it everytime that I had new content.

I never fully closed the window of my word file, just minimized it.

there was one day that my file changed the name for Word_File_(something)... It was just the original document and I continued to save it, thinking that was like a copy of my original document in the same folder. So, when I finished my document i closed the window and when I was trying to send it by email, i could find the last changes.

I searched everywhere: recents, finder, My Mac, spotlight, the original name and the name that it was saving last, but I can not find my document.

any other suggestions of folders related to word that i can be?

Thx
