Ovulation test kit vs. progesterone levels - thoughts?

I used clear blue ovulation tests to pinpoint ovulation. I got 'high' fertility on 6/3 & 6/4 and then 'peak' on 6/5 & 6/6, so according to those tests, plus the glow prediction, I should have ovulated around 6/6. Progesterone 7 DPO was 1.7 and 9 DPO was 5.1. My doctor called to say that, based on progesterone results, I ovulated on 6/13 not 6/6, which would be a full week later than I normally ovulate and contradicts ovulation test, which looked at estrogen and LH levels.

So... any thoughts on this one? Is it possible I'm actually pregnant and progesterone is just slowly rising? It seems odd to me that I would suddenly ovulate a full week late (it's usually within a 1-2 day window) AND the clear blue tests (all of them...) were faulty.

Just looking for some other thoughts on the matter since I have no idea what to make of it.
