AF late w BFN

Ashley
Ugh. AF was due yesterday and she never showed...I took a HPT this morning using FMU and got a (clearly) BFN...UGH! What the heck?! The TWW is tough enough but now this?! I have cramping today but not even a slight bit of spotting or anything.
Anyone else get their BFP days after getting a BFN when AF was late? If so how many days did it take to get your BFP?!
