How know if current item was deleted?

I created a policy on a library which it's run after a month of document creation date and run a SharePoint 2010 workflow Workflow A which it gives the document creator a period 5 minutes to fill document properties.

When the document creator fill the document properties then there is another workflow Workflow B on the library which it moves the document to another library.

I need a way to know if the document was moved by Workflow B after Workflow A running.
