AF, just come already and get this over with!

Kate • 32. Canadian. TTC #1 since Aug. 2014. PCOS. Endometriosis. MC in June 2016. Uterine septum removed January 2017.
I am super frustrated! I'm on cycle day 39 (!) and I'm 19 DPO. AF is 5 days late; still no BFP, not even a faint line. 
At this point, I just want AF to show up so I can start a new cycle and try again! I'm getting so frustrated!!
