Get the current category with shortcode

Hi,
Is there a way to get the current category on the shortcode? Because I would like to add a Load More to the WP Archive page (category filter) and instead of creating one shortcode to each category I would like to create just one shortcode that gets the current category. Is that possible?

Example:
<?php echo do_shortcode(‘[ajax_load_more post_type=”post” posts_per_page=”5″ category=”CURRENT CATEGORY” offset=”10″‘); ?>
