here's what i think about that. as far as this widely-held belief that after your first opk you should stop testing--- after a lot of experience with this myself, and listening to a lot of other ttc'ers experiences, i think you are absolutely right to continue testing, here's why...
in a perfect world, we get our first pos opk, and we o 36 hours later, right on schedule, right? not so fast. in a lot of cycles, this is not what happens. sometimes for whatever reason, we get a surge, it isnt quite enough, we dont o, and we get another surge 24 hours later, 48 hours later, or a week later, who knows, and that's when we o. this is not uncommon. if you arent temping especially, this is a recipe for a missed egg, because you get 1 pos opk, think you are o'ing, bd, and then stop, thinking your fertile window is passed. even with temping/checking cm and cp, it's confusing. this is why i am now continuing opks clear through until my temp confirms ovulation with a sustained thermal shift and crosshairs. it's also possible to o twice, even though we are taught this will always happen, if it does, within 24 hours, the truth is we dont know all the answers...

this isnt even taking into account the fact that you might get a dud batch of opks, or even just one defective one, and it throws you off. we know for sure that hpts are often more sensitive than they claim to be, we know this from betas. if you get an opk that is more sensitive- this is a BAD thing, because you can end up with a false positive. we dont want opks to be positive below 40 mlu, because we always have lh floating around, we want to know when we have a true surge, not just an uptick.
the other thing is, if you do continue taking them, take them correctly- best time being 2 pm and never with fmu (unless the instructions say to- but i dont recommend this brand either,) and they are TRULY positive, not misinterpreted, (and this is why i do NOT recommend any brand that says you have to have 50% of the line whatever, too much ambiguity open to interpretation!) if you truly have more than 4 days of opks pos in a row, this is a possible sign of pcos, and that is information that is good to have sooner rather than later in your ttc journey. there are many things that can improve conception and pregnancy rates with pcos, but it's something you need to talk about with a hcp.
ttc- in your case, if it went fainter, if it was not positive in the middle there, i would say you had the surge/no o/re-surge scenario. keep watching cm/cp, even if you arent temping. you can even start temping tomorrow am- run and get a bbt therm at any pharmacy or even grocery store. you may still have time to get information that would be helpful this cycle, especially if you are not o'ing in the next day or two and these opks are false alarms.
