Did I O , even tho no + OPK??

Delsie • Momma to Jagger ( 3 ) & finally expecting baby #2 OUR rainbow - April 20th,2016!! After 3 loses I'm so nervous! :/
I test with OPKs twice a day so it's unlikely Id miss the surge , these are my tests from yesterday and today ( both neg ) but I had a huge temp rise :s I have a bit of a headache maybe that's the cause for the rise ? And I have a 33 day cycle so sshouldnt ovulate till cd 20 not 15 :s
