opk and lh surge...quite near?

Lara

So these are my opk tests, i'm on day 14 of a 28-29 days cycle. I think i'm near my ovulation day...how many days do you think i have left from the surge? i'm following the egg meets sperm method.. and can i keep ok testing once a day? i usually test at 3 in the afternoon when i come back from work..
