Is this normal?

I had a beautiful baby girl baby 5 months ago. I have had a consistent period like clockwork every month since. I am breastfeeding but did not miss a period at all. This month.... nothing. I'm about a week late but tests say I'm not pregnant? Am I broken?! lol what is going on?!

*I called the dr and they told me to wait and test again in a few days. Call back with results. 😡
