Pregnant or no!?

So 3 months ago my period was the 12th. Last 2 months, my period has been the 6th. My period is always on time or that one time it was 6 days early. This month it was due the 3rd, never came. Then I was like okay maybe the 6th, well now it's the end of the 7th, still no period. No cramps. None of my usual signs. Yet every test I had taken up until the 3rd was negative. I took one today, NEGATIVE. Not even the smallest faintest little line! 🙄😤 i don't know what to think?
