OPK question

[monroea]

I'm still a little confused about how OPKs work. Can your tests get darker and then lighter without actually getting a positive? What would cause this? Does it just mean that I'm irregular and haven't yet ovulated or could it be that I missed that peak? I test the same time every day.

I think 2nd and 3rd are positives

There are some ICs brand that aren't good quality, doesn't show true positives
