Did I ovulate?

Stephanie
I got negative ovulation tests all throughout my fertile window but this morning bbt spiked a whole degree. I'm wondering if bbt still rises if I didn't ovulate or if it means I definitely ovulated. Today is CD 20, Nov 30. 
Nov 23 "low" test result with clearblue advanced. 
Nov 24 "low" on clearblue advanced. 
Nov 25 "high" on clearblue advanced. 
Nov 26 "no" with target up and up brand. Baby dance today. 
Side note, I only had one more clearblue test left so I saved it for Nov 27.
Nov 27 " high" clearblue advanced. "No" up and up brand. 
Nov 28 "no" with target up and up brand 
Nov 29 " no" with target up and up brand. Baby dance today. 
Nov 30 " no" with target up and up brand (am test, I usually do am and pm tests)
