interesting info I read on multiple OPKS

I posted a few days ago (Monday) of an opk I took where the test line was clearly darker that he control line and was soooo excited to get a positive. Took another one today (Thursday) for curiousity annnndddd looks pretty positive to me (picture below) difference is, the control line and test line are the same color this time. I did some google digging and here is what I read from someone else online (screen shot also posted below) I do have irregular cycles but i started to drink fertilitea this month after the reviews I read. Hope this helps some of you out & hoping my real positive was Monday since I put a lot of work into that one 😜😜 what do you ladies think??
