It takes about two weeks for Google to Index your site properly. Have you submitted the site map generated by Yoast SEO? If not it’ll take longer. A few days just isn’t realistic.
Also, It really depends what your robots text states?
To see which URLs Google has been blocked from crawling, visit the Blocked URLs page of the Crawl section of Webmaster Tools.
You need a robots.txt file only if your site includes content that you don’t want search engines to index. If you want search engines to index everything in your site, you don’t need a robots.txt file (not even an empty one)and you don’t need to no index all the other content.
You have indexed only pages and posts and no indexed all the other content – did you want to do that?
