One day late for AF and still a BFN...?

Today is 14dpo and I was supposed to get AF yesterday. I did cramp all day and kept going to the bathroom thinking it was going to start and it never did. Then I cramped first thing this morning, but now is gone, but still nothing. BFN yesterday morning and this morning. I had some symptoms last week such as cramping on 7and 8 dpo. Spotting late on 8dpo and the morning of 9dpo but just a tiny little bit. So now I am just waiting for AF or a BFP. Has anyone else had any similar symptoms to this. I've had other symptoms too, but don't feel I can necessarily attribute them to pregnancy symptoms because they could be or couldn't be. I'm not trying to psych myself out for a BFP, I'm prepared for either. I just wish one or the other would go ahead and happen.
