Exclude nomenclature and glossary from page count

Question

I want both, the nomenclature and glossary, be excluded from the page count. They are not appearing in the toc yet they still increases my number of pages. How can I say from which page on my total number of pages shall begin?

\documentclass[12pt]{report}
\makeglossaries
\begin{document}
\begin{titlepage}
 ...
\end{titlepage}
\begin{abstract}
 ...
\end{abstract}
\newglossaryentry{cdc}
{
name=CDC, description={Center for Disease Control}
}
\newglossaryentry{lstm}
{
name=LSTM, description={Long Short Term Memory}
}
...
\printglossaries

\nomenclature[M]{$\phi$}{...Activation function in a neural network}

\nomenclature[M]{\textbf{v}}{...bold and lower case letters represents a vector}

\printnomenclature
\tableofcontents
\chapter{..}
%myblabla
\end{document}
