Why can’t AF just show up if she’s gonna come???

Y’all, I’m on cycle day 77! I’m taking another pregnancy test tomorrow, but this is getting ri-damn-diculous! I’ve been cramping for a week now and I’m still not bleeding. I did cramp like this with my son at the beginning of my pregnancy. I’m just trying to not get my hopes up that I’m pregnant again. Why should it happen now if we’ve been trying for a year next month with no success?
