Bbt temp, which one do I go with?

Brandi-lea • Khaleesi-May Dizney Van Vliet - my precious daughter born on 23.6.15 👶🏼🌸
So at 5.50am my DB woke me up asking what time it was. I got my phone out and told him the time then fell back to sleep. At 9.15am he woke me up with a kiss as he was leaving for work, I took my temp and got 97.02.  
​I then fell back into a deep sleep for 3 hours and 20 minutes then woke up At 12.35pm. I took my temp again and it was 97.65. 
​Now here's my problem .. If I go with 97.02 then that's a drop in my temp and I'm due to ovulate today.. But, if I go with 97.65 that's a big rise in temp and towers over most of my temps.. Which possibly could confirm ovulation from yesterday..
​Which one do I go with?
