Getting antsy

Trying for #1....I'm in my TWW....AF is supposed to arrive Monday Oct 2....hubby and I did BD just about every day during the week I was supposed to ovulate, got the smiley face on my opk....the past five days or so I've had light tugging "cramps" and been having hot flashes (the past 2 nights he and I swore I had a fever but temp was normal), having crazy, crazy, vivid dreams and been exhausted. And my strength has been way low (I'm a power lifter and normally the week before AF I am crazy strong). Couldn't wait any longer so took a test first thing this morning and got a BFN....I am disappointed but I know it isn't over till AF sings!!!!
