I have the same problem with my writing: not sure what genre I fit in, if any (though, I assume, we all fit into one category, at least). I write the story devoid of any concept of genre, letting the characters and the situations play out as need be. I believe I edge towards upmarket fiction but possibly I'm over-selling the work. Contemporary seems so vague, though. I'm just about at the querying stage so definitely need to figure this out soon!
