Am I ovulating?!

So here's my chart for this cycle and I'm also adding my opk tests for today. Today and yesterday my opk looked like this one looks positive but one looks negative. I use the clear blue advanced digital and another brand called answers. The answers brand appears to be positive but the clear blue is showing up as negative. Going crazy! Which one do I go with?! My chart has no spike in temp

either which makes me confused!
