Confused on ovulation

Kim • TTC #3 since March. Have a baby girl born March 2013. Baby boy born March 2016.
Ok so I've been doing opk everyday and was close last nite but not positive yet. Took my temp this morning and had a spike and just got a positive opk. So I'm confused if I ovulated last nite or not yet? My temp says I did but my test says I'm about to now. I did take my temp 2 hours later than normal so I don't know how much a difference that makes in temp? Any insight would be helpful thanks. :)
