What are my chances of being pregnant?

My stomach has been feeling weird lately, slightly decreasing in hunger, minor cramping comes and goes, had a pink discharge for 3 days (very skanty), light brown discharge for 1 day (only saw it once or twice), and a darker brown for 1 day (saw it once on my panty liner). And right now I'm 14 dpo. Still no positive. Tested right when my alarm went off around 7:30 this morning. Getting hot flashes, and AF was due today and it hasn't come. Do I still have a chance if I'm 14 dpo and STILL haven't gotten a bfp??
