Chart help- did I O?

Ally
I'm new to charting and wanted some opinions.  Is my BBT rise enough to indicated that I ovulated on CD 17? I know my OPKs were all negative but I read that it's not uncommon to miss your + and that temps are a better indicator. 
By the way- as you can see I discarded a few very high temps before CD 17 because they were after nights when I barely slept.  
TIA!
