Am I going crazy??? 😬

My hubs and I are TTC#1 together (1st for me and 2nd for him). I am currently 8DPO according to my CBAD OPK results. The past few days I have been very edgy.. I go from psycho bitch to cry baby to wanting to just curl up and go to sleep! People at work are driving me insane over stupid crap, when usually it does not bother me!! I have already cried twice today and I am not a crier at all! I have been crying over tv shows, commercials, text messages... I'm trying not to read into anything just yet but why do I feel like this?? I feel like I am going crazy!!!
