So, does this mean I'm not at all??

I took the 2 blue dye tests and seen vvvvfl in both of them, then I took the first signal test and completely nothing! So does this mean those 2 blue dye tests were invalid. I'm 2 days late on AF and been super tired and having cravings for a while now so I'm just confused and I'm not sure when I ovulated since my periods are so irregular.. 😫
