You won't see your temp start to shift until the day after you ovulate. The opk tests also don't guarantee you will ovulate. They just show the lh surge in your system which happens before ovulation. You can have an lh surge an not end up ovulating. That is why you need to wait until you see three consecutive high temps to confirm ovulation.

I just looked at your chart. It doesn't appear to have the shift yet. I know they say that not all women see a temp shift but since you clearly had one last month, I would guess you should see one this month also.
