WordPress creates feeds at
[site_url]/feed/ by default. Check there e.g.
There should also be a link added to all pages in the
rel="alternate" type="application/rss+xml" title="website title Feed" href="[site_url]/feed/" />
The title is usually pulled from your WordPress site description, editable in admin area.
With this header link users with an RSS extension can 'discover' your feed. You can also add a link on each page of your site (recommended) to the RSS feed stream (http://www.w3schools.com/rss/rss_publishing.asp).
