So emotional..

Im so frustrated seeing a BFN every time I test.. I am 12dpo and AF is due tomorrow.. I have none of my "normal" period symptoms.. normally about a wk b4 my boobs are so sore it hurts to even wear a bra and I eat everything in site.. now I am not even a little tender..I'm exhusted and nauseated, I can't even stand to eat gum or mints they make me want to vomit..I just feel off!! and yet I keep seeing a BFN staring me in the face.. ughhh anyone else in the same boat?
