11 DPO feel like garbage, FRER BFN-TWW is torture!!!

I'm 11 DPO, feel AWFUL, no appetite, feel nauseated, sore breasts, cramps he last two days (but they are starting to go away) I've taken 2 FRER, both BFN, AF not due till Tuesday, not sure if AF is going to start early or if I have a BFP in my future. THE ANTICIPATION IS KILLING ME! I don't normally feel this crappy prior to AF, cramps yes but never nausea and low appetite, usually I want to eat everything in sight. Anyone else going through this? Misery loves company!!
