database error fixed, can I get my posts and stuff back?

I got an error connecting to the database this morning which I fixed in the wp-config.php file. I had issues setting up the database(s) with the host at the beginning so I made extra dbs not knowing what I was doing. I’m assuming one of them was finally deleted and it threw off the login. However now, even though my theme and images I uploaded to them are still there, I had a new WP admin login and am back to the beginning as far as posts, plugins, everything I worked on. I’m pretty sure I did a back up but how do I get to it? I’m using Dreamhost if it matters. Thanks for any help!
