I'm not an expert, so hopefully someone else can expand on this sort of beginner stuff.
Check to see if your program was set up with an auto-default to auto-save every few minutes. Open Word, click on the multi-colored circle in the upper lefthand corner, at the bottom of that menu will be "word options". Click on that. On the lefthand column will be "save". Click on that and see if auto-recover is checked. If it is, it will tell you where auto-saved documents are kept. You can go int that file area and see if you can find your stuff.
