Missing pages, but note in Trash

As of this morning our website was functioning with no issues. A few hours ago, all but 5 of our pages are gone. We had over 40 and can’t figure out what happened. There are 10 old pages in Trash, but they’ve been there for awhile. For some reason I don’t think the pages were deleted maliciously or accidentally due to the pages in Trash.

All media and all forums haven’t been modified. All updates have been applied. I don’t know how to check for any corruption in MYSQL, but not sure if that’s the issues.
