Categories and Tags not working!

Category and Tag archive pages only query for the post post type. If you want custom post types to appear on those pages, you need to modify the query via pre_get_posts to add additional types.

function wpd_womens_blog_taxonomy_queries( $query ) {
    if ( ( $query->is_category() || $query->is_tag() )
        && $query->is_main_query() ) {
            $query->set( 'post_type', array( 'post', 'womens_blog' ) );
    }
}
add_action( 'pre_get_posts', 'wpd_womens_blog_taxonomy_queries' );
