Blue dye vs. pink dye tests

This morning (against my better judgement) I took a HPT. It was a blue dye test and came up with a BFN. But I feel unbelievably pregnant. Tired, extremely sore and big breasts, slight cramping and nausea, etc. Should I wait a few days and test with a pink dye test? AF is due 6/21. Have any of you ladies seen a difference between the two?
