Accessing my blog

Having just downloaded WordPress to my website, I am very embarrassed to admit that I cannot access my blog. I have an admin URL that lets me make changes but I do not appear to have an address that I can give to people that will access the public blog. The site to which it was installed (www.weddingessentials.ca) just opens to my regular website. I have a feeling that I perhaps should have entered a special address during installation. Is there something simple I can do to generate an access URL for the blog alone? Many thanks.
