Alright, now I'm just pissed at my body. My cycle has been like clock work till this month. Which got my hopes up, yet test after tests has came back nagative. Now I'm 6 days late with super sore breasts and still no do sign of AF. What the heck gives?!?! Anyone else deal with this? I'm not under anymore stress then usual.
