Could I be pregnant at 14 DPO with BFN?

Hey ladies, I need some help! I'm 14 DPO and took a test this morning and got a BFN. I was expecting to start bleeding today but I haven't yet! What's going on? Am I going to start bleeding in the next day or so? I was just wondering if anyone's gotten a positive after 14DPO. I had moderate cramps on 12DPO and I normally never cramp before I start my period only when. Could it have been a late implantation? I just want to start bleeding already to I can plan out the next cycle and figure out what I want to do differently next time! Thanks for the advice!! When will AF show???
