This is normal behaviour, as I understand it. When you load the page post-new.php, you run this function: $post = get_default_post_to_edit( $post_type, true ); where the second argument stands for $create_in_db. If true then this part is executed: if ( $create_in_db ) { $post_id = wp_insert_post(…); } inside get_default_post_to_edit().
Help getting previously visited pages ID
get_page_by_path() should help you here.
