Positive? So confused!

I have been taking FRER since 8dpo (testong out trigger shot), and yesterday, at 12 dpo I finally got a definite positive. Problem is, at 8dpo my nurse told me to come in for a blood test and it was negative (definitely too early). So I have been tracking how dark they get since then.. Today, 13dpo, I tested with a blue dye the first time (they were out of FRER)

and got a VERY faint line, and now I am more confused than ever... I have heard the blue dyes aren't the most reliable.. would ou found this as a positive?

I will most likely go out and get a FRER and test this afternoon to keep myself sane..
