Ovulation question please help.

Amber

I've been getting negative opk. I have also been tracking my temp this cycle as well. Is it normal to have negative test, but a rise in temp. My temp this morning was 97.95. My normal temps this far have been maybe 97.5 or a little higher, but not this high. Is it possible to have ovulated even with a negetive test? If this is the case does it mean I've missed my chance?
