Why does the darkness not seem to be changing?!

This will be my third month taking the clear blue ovulation test and I’m two days from ovulating but the color of the LH line is still so faint! Each time I’ve done this, it gets progressively darker but this month it’s stayed so light, especially for being two days before ovulation! Unless maybe I’m abt to ovulate late which would be very strange as that’s only happened once before (right after my MC last nov).

Thoughts?

Ps the pic hardly shows the line at all but it’s there just super faint...but why when I’m so close to ovulating??
