Was your first pos opk actually pos though? From memory it was the darkest but still not quite positive.... sorry if I'm wrong but saves me going back a heap of pages lol. As for the creamy cm yep I would consider that strange too however that's probably the least reliable no matter how by the book it has always seemed to be, I used to swear by my cm until I had a couple cycles that didn't line up. I'd be much more inclined to trust the opk but that's just my opinion and I'm no expert. Diluted urine can affect opks for sure however when you're at your peak (surge) you should still see a pos even if its only 'just' positive as in line colour
