Changed WordPress URL and can't access blog or admin login

Hi,

I’m in desperate need of help, preferably in very “dumbed-down” language. I began the process of migrating my Blogger blog to self-hosted WordPress a few weeks ago, purchased web hosting through Bluehost and set up the WordPress page. I previously purchased a domain through Google (Enom) at http://inhermakeupbag.com, so I got the WordPress site set up exactly how I wanted it and then planned to point my name servers from Enom to Bluehost.

Earlier tonight, I pointed the name servers to ns1.bluehost.com and ns2.bluehost.com like I was advised, and then went over to WordPress to change my URL there. I accidentally changed BOTH URLs (not being tech-savvy here), and now it seems I can’t access my blog at all. When I type in my domain, http://inhermakeupbag.com, I get an error page. My temporary WordPress URL/wp-admin URL don’t work, either.

I hope this makes sense- I have no idea how to fix this as I can’t access my blog at all.
