Should load next month when there is not any post in current month

Hi Sir/Mam,
I am using your plugin in my website, it’s working very well. But i have an issue. I am using this plugin to show post relative to month. This plugin does not show next month’s post when there is not any post in current month. It means i want to show that month in which i have post. It should show next month post on load and without clicking anywhere.

I hope i am able to explain what i need. Please help asap.
Thanks
