Did I ovulate? Chart...

Aubrey
My Dr. Told me not to fuss with BBT because "if you're having sex every other day, you'll get pregnant.." 
...however, I felt recently that I should start BBT anyway because I have irregular periods (haven't had one without meds in 2+ years) & I wanted to know if my body was ovulating...
​ 
​ANYWAY- this is my chart, in your opinions, does this look like a ovulation between 10/17-10/19? I have no clue how to properly read them. 
Thanks!!  
​(Ps- did not start period today, that was projected)
