Opk question

So according to this appt I am due to ovulate tomorrow or Thursday i have been doing opks since Saturday because I was having some weird cramping and a wet feeling I thought it was abnormal for me since I just had done with my period last Wednesday. The opks I have done they have been negative but the test like is getting more solid and little darker, but it's still very light, I have been testing 2-3 times a day since I have seen LH surge can happen at any time.

Question is by when should I be seeing my positive LH? If ovulation should be happening within the next couple days
