Period or pregnancy

I’m on day 41 of my cycle. My last period ended and then a week later I started spotting for about a week and a half... this has never happened before.

At 6 days of my missed period I took a test but it was negative. I took another test at 10 days of my missed period and it was also negative. I still haven’t had my period. I’m 12 days late currently and nothing.
