Firstly, check if your domain hasn't crawled yet. Write 'cache:yourdomainname' and click enter to see when the crawler last visited on your website. If it shows 404 error then the crawler has not visited your domain. To make your site index, Inspect the URL in Google Webmaster Tool and request the same.
You can check if your URL has been indexed or not by searching on Google as 'site:yourdomainname.' The indexed web pages of your website will appear in the search result.
