Lost post, but said draft saved?

Last night I started a post on wordpress for the host ‘backpagefootball.com’. I closed my laptop overnight and came back to write it this morning, I finished it off at about 11.30am and went to submit the post for review before getting an error message, when I refreshed the page it had logged me out and I had to log back in again and when I did so the draft which ha d been saved was the one from last night – I effectively lost the whole thing other than the two lines of notes I had written last night. I don’t mind doing it again if I have to but as (when I was writing it this morning) it kept saying ‘draft saved at..(time)…’ I am certain there must be some way of retrieving it? It must have saved somewhere?
