Line eyes or vvvvfl

Okay so I use to be in this group but my pregnancy ended in a miscarriage at 8 weeks in June. This is my first cycle since and I thought I saw a vvvfl on test strip I took earlier (8dpo) So I went and bought another test and another vvvfl but it was blue dye so I don’t know if I trust it. I’ve heard ppl get false positives from blue dye all the time. What do y’all think? It’s honestly really hard to believe honestly 😭🤦🏻‍♀️
