Blue dye tests

Brittney
I absolutely hate blue dye tests. But my period was 3 days early, lasted for 24 hours, then stopped. Now (48 hours later) I am spotting.  My period is NEVER early, I am always regular. Anyways, I stopped and bought a cheap test and I know the blue dye has a bad rep (rightfully so). And this is what I got....
So my question is, do a lot of you women have false positives like this (when using blue dye tests)?
Or maybe I'm just delusional and it's not positive at all?
