Big Fat Negative - as always!

I know, I know. I'm to early to test. My AF is 02/27 due. But I tested today.
And of course it was a big fat negative.
I just tested because the last four days I've been so nauseous and I had hot flashes and headache plus my nipples are so sore! They're never so sore!
Also my dream today was about going to target and buy everything to tell my husband were pregnant. So I woke up and thought I should test... Nothing. I'm so "heartbroken" - again.
