3 days late, 2 BFN's ....

Claire • Ttc baby #2!!!
So I tested on day AF was due, then again 2 days later, both with BFN's!! Has anyone had BFN then later got their BFP if so how long after???
​It's soooo frustrating! If I'm not pregnant this month I wish AF would hurry up and show so I can move onto next month!! Grrrrrrrr!!
