Getting a entry link created by current User
You need to fetch the entry with one() keep in mind in order to be able to be an author the user needs the permission to create entries in that section 

{% set myEntry = craft.entries.section('userProfiles').authorId(currentUser.id).one() %} 
&lt;a href="{{ myEntry.getUrl() }}"&gt;My Profile&lt;/a&gt;


You should also consider to code defensively and check if there is a current user and if myEntry is not null
