BBT temperature

Hello!

So my period is late, but my BBT haven’t risen yet, my temperature have been around 96 for over a week now, and even when I had drinks my temperature never went above 96.9. I did switch thermometers, but even my last one was giving me 96 temperatures.

Is this normal? do you guys think my thermometer is meh or maybe I am having a anovulatory cycle?

Thank you ladies!!!
