No rise in BBT but LH Surge

Alex

So I’m needing some more help looking at this.

This is my first cycle tracking my bbt.

I clearly peaked on CD 15 as seen in the test strips below and shown in orange on the chart.

But I’m now 1 day after predicted ovulation and my BBT isn’t rising at all. Staying very stagnant. Could this mean I’m not ovulating??
