XML Sitemap – google is not indexing my posts

I have submitted the xml sitemap over google webmaster tools 7 days ago
not errors found (I am using wordpress, SEO by yoast plugin)
only my homepage and blog page got indexed by all the posts are not being indexed…
is it because I have the blog list posts in another page (not the homepage)?
in the settings->reading I have unchecked as default the discorrage from index
what I have notice in the xml files is that the:
post-sitemap.xml – website.com/blog is set to daily priority 100%…
XML Sitemap – google is not indexing my posts
