How close do you think i am to the big o?

Please can someone tell me it's almost time? im on CD15 already and I'm tired of peeing into cups every evening... I usually get a positive opk on CD12

or CD13 (tracked for 2 cycles this is the 3rd) i have a 26-28 days cycle although my last cycle was 24 days...

***Sorry for the blurry picture, i had to take this same picture 5 times to get one this clear.
