Invisible posts

Hi.

When I view the Categories there’s one saying “4 posts” though there’s actually only one visible post on the page. (I’ve only done one post so far.) Where are these other posts? And how do I delete them? Maybe some other user has saved a “Private draft” but how do I view these?

Would really appreciate some help.
