is this my positive?

this is my opks for past few days (im obsessive its usually morning noon and night).. i have really long irregular cycles, so my last AF was 16th Sept (previous to that was 24th July).. so i feel I have to use opk to know exactly when I'll ovulate. The one 5th from bottom was yesterday afternoon and myself and hubby were convinced it was positive..then last night,this morning etc the lines weren't as dark.. the bottom line was about half an hour ago and it definitely looks positive to me.. is this it? lol 😂🙈 I'm so confused when my 'peak time' is xx
