Problem with Layout

If someone could please help me it’d be much appreciated!!! My blog is located at http://www.ohmygoodiesco.com/blog please take a look and tell me if you can, why the layout is off to the side and doesn’t line up right.

The person who did my coding has used WordPress before and on her site everything is fine but on mine she can’t figure out why it isn’t lining up right.

Every other page on the side is aligned correctly but the blog page. Thanks in advance for any help you can give us!!!
