6 Days Late, still BFN ???

6 days late and im pretty sure i see now happy line yet. i have no signs of af symptoms. Usually my breasts are hard and sore a week before AF arrives. This time around i got nothing. Mild cramps here and there but my breasts are normal. I have been extremely tired to the point i wish i could call out of work each morning haha. Just yesterday i mentioned that my tastes buds were quite off. Like nothing i had tastes normal. A few people said it's a pregnancy sign. Ughh, help !!! i took a test and i see nothing. Yes i know blue dye sucks lol. But I'll wait a few more days to try a pink dye.
