Its really odd that you had a positive OPK 6 days in a row.... My understanding it that they detect when a LH surge is coming within 48hr.
Do you happen to have PCOS? I heard they don't always work with some women.
It looks like you defiantly ovulated, but your temperatures are hovering near your coverline.
It took me a few months to get my pattern to know when it was different.
But as I've learned Ovulating is half the battle!
For me (and really just for me) I would have a temp begin to drop 10dpo and it wouldn't go back up at high as before again.
That was one of the clues for me about this cycle.
I wish you the best of luck either way.
