Late AF- how many of you were late?

Hazie
I'm pretty regular working 1-2 days of my AF. This cycle is odd, I have no pms symptoms and I'm 4 days late. I tested, got a BFN
​Did any other ladies test BFN after late AF and end up pregnant? I have also asked this on the "trying" page, just looking to hear from Mamas to be!
