So confused

I'm so confused. According to everything I should have ovulated around day 16 or 17. Had a positive opk then negative next day. Cm follows all that as well but I don't see really a temp spike. Does it even look like I ovulated at all? I'm starting to get very frustrated. I got a new thermometer for next cycle cuz I don't feel like this one is really accurate since I took my temp like normal then took it again and there was over a .2 difference. Then my temp this morning is super high. No other signs of ovulation though. Why does this have to be so complicated?!?!?
