Blue dye question

I knowwww don’t buy them use pink dye only... I found out I was pregnant with my first on a blue dye so I trust them to a point. Would the line show precession if it was a false positive? I’m so hesitant. I’m not getting excited af is due in 2 days I’m waiting to retest with a frer but these were taken starting 7 dpo, 8 and 9 dpo so I was thinking I had a good shot at them being true. I don’t know . The last pic is a comparison of when I found out I was pregnant with my first to the most recent pregnancy test this time
