[Tex/LaTex] Book: Top right side page numbering

numberingpage-numbering

I am trying to place the page number at the right top of the page, and it is working in the chapters, but at the beginning of the document it is not working as I was expecting. This are the lines I am using to set the page numbering:

% Page numbering: top right
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancypagestyle{plain}{
    \fancyhf{} % clear all header and footer fields
    \fancyhead[RO,RE]{\thepage} %RO=right odd, RE=right even
    \renewcommand{\headrulewidth}{0pt}
    \renewcommand{\footrulewidth}{0pt}
}

I am getting this:

enter image description here

First, I am getting that horizontal line at the top in several pages. In addition, this page has a number, and it is not supposed to have it, and other pages too. Finally, the pages that have the contents are numbered too. How can I solve this issue?

P.S.: I need no header neither footer.

Assuming you are using a standard class, you should be using either titlepage or \maketitle to create your title. This automatically sets the page style to empty or plain. Presumably, you are not doing that, so you are getting the fancy style which includes headings and a page number in the footer by default.

Probably, you want to set up a suitable style for standard pages.

But, in any case, if you do not use titlepage or \maketitle or equivalent, you should say \thispagestyle{empty} on the first page to avoid both header and footer.

This is, of course, a wild guess (see comment). Hence it could be quite wrong. Without a minimal example, it is impossible to do better.
