my posts are deleted from 7.19.-22.2011

I just noticed that my last 2 posts are deleted. i cannot seem to find any history on my wordpress page, but i did find history in my library. When I clicked on it it said there wasn’t a post… weird. I do see that akismet has marked something as spam. How do I see what is marked as spam? How do i find my wordpress database to see my history? How do I find out if something has been deleted?
Thank you
