7-8dpo positive opk bfn?

Ok so I’m about 7-8dpo and I confirmed my O day with opks on the 29th or 30th. I don’t bbt since my son broke our thermometer 🤦🏻‍♀️ but I’m def a POAS addict so I used an opk today and a cheapie Rite Aid brand blue dye test. What can I say...they were on sale and I had a coupon 🤷🏻‍♀️ so anyway... I never use blue dye tests and I feel like I see the faintest of lines but I can’t trust since I only trust pink dye tests (getting more pink dye tests in the mail today). But the positive (or what I think is a + or close to a +) opk has me scratching my head.

Anyone out there get a + opk that lead to a + hpt right after?

Here are the pics all taken within the time frame.
