feeling so fed up..

DPO11 and feeling so down, feel like i'm constantly crying at the most ridiculous things! I'm literally googling all kinds of sypmtoms other ladies had with their BFP's, linking and matching everything im experiencing with theirs.. it's completely ridiculous ? don't know whether to laugh at myself or cry! AF is due on sunday, not sure to test before or just wait and see if she's late? ..Anyone else going slightly insane in their tww?
