If your site is showing up in Google, it is indexed. You can also check to see which specific posts and pages are indexed by searching for them directly in Google.
Just copy the address of the page or post you want to check and type this in the Google search box => site: (paste your address here) and click enter.
Google will then show you if the page is indexed or not.
If's it's not indexed, go to
https://www.google.com/webmasters/tools/submit-url?continue=/addurl and enter the address there.
This allows you to tell Google to crawl that page or post to try to get it indexed.
Don't trust the SEO tools. Check your pages with the source (Google)
You will never go wrong by doing that.
