2 days late 14dpo no bfp yet

Just wondering if its likely to get a bfp after 14dpo? I NEVER miss my period its always been on time 27 day cycle and only once over the past yr has it been 29 days. Been testing with frer but nothing yet. I don't feel my period coming at all and I usually get these horrible cramps right before. What's the likelihood of me getting a positive later in the game? How many days passed my missed period should I go to my doctor?
