Being new user sometimes common sense usability roadblocks are easier to see. So I will try to provide some insight into my first try experience. I decide to use Writer to create a simple pdf to share some screenshots with a group of people. I have 9 screenshots, so the pdf would be multipaged. I open Write, insert images, when I need to move to the second page to insert images I was not able to easily active another page, it was not even clear to me how to do that. I tried to put curses after image but seems image was floating and not really inserted in page so when I tried to move to open space to the right or below last image inserted I was not able to. I could not find an easy way from the open document page to invoke a second page.
I think a better question, to ask first in https://ask.libreoffice.org/c/english/5
The way to "add another page" without content on the first page would be to insert a page break (ctrl + enter). Related to your question, you might also be interested in bug 146445. But as m.a.riosv said, better asked on our Question and Answer website. Thank you!
