When I copypaste data into Writer, my page count... Goes down?

I had 94 pages in my document, and when I copypasted in some information I had written up, page count went down to 91. This isn't the first time it's happened, and considering that I'm in the middle of Script Frenzy, when page count is very important, I have concerns with this.
