The day I was supposed to start my period (June 11) I spotted only once...could it be possible that that was my period for the month of June?! I'm just trying to weigh out all the options of why I'd be 18 days late from expected AF and still have negative Hpts. My next cycle is due to come on July 8....so I guess it's just a waiting game to see if AF will show her face. I still see my doc on July 19th...maybe I'll get a BFP before then...if not need to see what's going on with me cuz my periods are spot on regular every month.
