How To Get Rid Of a Blank Page in Pages for iPad?

How do you add a page or remove a page? I am so irritated that a few of my projects have added an additional page, so that when I print, it’s a blank page. I need to know how to get rid of the additional page.
I am creating patterns for quilting projects. I am doing it in landscape mode because I will be folding it in half and placing it in a clear ziploc bag that is 6×9. I am using text and pictures. I have no idea why it has created another page sometimes and there isn’t anything on it.
Thank you, in advance.
