OPK question

Not a pregnancy test, but this group is the most active i am in 😅 the top test was yesterday afternoon, and the bottom was this afternoon. I know the top is positive, but that dark of a line on today’s makes me wonder 💭 do you consider your ovulation to happen the 24-36 hours once you get a normal positive, or do you consider your ovulation to happen 24-36 hours after that test line is darker than the control? These are a full day apart. Also.. This is a ‘just for fun’ question, we have our bases covered in terms of baby dancing lol 😂
