Remove blank pages between figures in appendix?

Question

I am trying to make an Appendix with a few figures. My problem is that LaTeX inserts a blank page between some of the figure and I can't figure out why. It feels lika I have tried everything.

Here is a short example of how the code in the appendix section looks like.

\documentclass{article}
\usepackage[titletoc]{appendix}
\usepackage{appendix,float}
\addcontentsline{toc}{section}{Bilagor}
\appendix
% ToC of the appendices
\section{Utförande: forskningsöversikt}
\label{appendix:A}
\begin{figure}[H]
\centering
\includegraphics{Bilagor/Bilaga1nyy.png}
\end{figure}
%Kommer bli bilaga B
\section{Kostnadskalkyl}
\label{appendix:B}
\begin{figure}[H]
\centering
\includegraphics[scale=1]{Bilagor/kostnad.png}
\end{figure}
\section{Lathund för kalibrering av friktionsmätare}
\label{appendix:C}
\begin{figure}[H]
\centering
\includegraphics[angle=-90]{Bilagor/BilagaC1.PNG}
\end{figure}
\begin{figure}[H]
\centering
\includegraphics[angle=-90]{Bilagor/BilagaC2.PNG}
\end{figure}

So greatful if anyone can help me!
