4 days late and no BFP

I am so bummed. I am 4 days late and nothing. I have taken 2 test and both BFN! I really thought this was my month. I have been TTC for 9 months already. Its ridiculous. So many women get pregnant so fast and I am sitting here kicking my feet in the sand. Yes I understand that women are different and it can be easier for some. I thought the amount I have sleeping, the nausea, the heart burn, my sore nipples were the ones. I don't feel like AF is coming. Usually I am moody and boobs are hurting like crazy when the bitch shows up but I have none of that. I am been feeling some lower abdomen pressure and told my self well here she comes and nothing. I wish my body would just choose one. Either BFP or AF. BUT Please stop playing with my heart. It sucks to feel like you cant do your job as a women correctly.
