I am so confused and need some opinions!

Hey all! I’m around 7/8dpo. I woke up this morning and decided to impulsively take a test knowing it would be negative bc I’m so early. But, it came back with a very obvious pink line right away! So I grabbed another of the same brand and a frer to test the same fmu I used in the first test. Those came back BFN, completely confused and needing more answers I ran to the dollar store, got a blue dye, and used the same fmu. I only looked at it for the first 5ish minutes as I saw it was negative also. So I put them all away and tried to forget it. I went back to look and the blue dye had an actual blue line (this was about an hour later). So I decided to do a 5 hour hold and use the same test that was positive.. and that came back negative also. The photos are in order in the timeline. Is there a chance I picked up some hcg with the first test and the blue dye but the others are false negatives? Or did I get a false positive this morning with my first test? Anyone experienced something like this?? Thanks!
