Opk positive or negative

Ava
​the first opk is cycle day 12 in the morning 8am 
​The second opk is cycle day 13 in the morning 8am
​The third opk is cycle day 13 in the evening 5pm 
​To me, it looks like it's positive on the 2nd one on cycle day 13 in the morning is positive, while the others are negative. I have a 28-29 day cycle. Hoping that this cycle I'll get my BFP :D. Any help is appreciated and welcome ladies, thank you.
