Could I be?

Jazzmine

From the pictures I'm a bit thrown and according to this app I am 3 days late. I've took pregnancy test and their all negative so it seems as if AF is just taking her time. I've used pre seed this cycle to see if it helps, from April 8th to the 11th I was cramping but still no AF. My cycles aren't consistent which doesn't help either. I dont know what else to do besides wait around for AF, so that I can start over.
