Still have a chance??

Anna • Married for 6 years, expecting baby boy #2 in June!
14 DPO today. AF due yesterday, but still no sign of her. Tested this morning with a BFN. CM has been really dry until yesterday and now it's thick and creamy (TMI-sorry...). Sore bbs started at 8dpo, and today I've had really bad cramps (not quite like AF) and diarrhea. 
What in the heck do I make of that?? Do I still have a chance of being pregnant?
