Kidney infection, TTC, and AF

Sydnee • Married. 21
Okay so glow said that AF was supposed to be here sept 29. It did not show up. well the next day/night I was hospitalized for a serious kidney infection, all is well with my kidneys now :D but AF still has not shown up. I've have glow be off by a few days before but now we're talking 6-7 days off. I have no signs of it starting. And wondering first if I should test or, does anyone know if and if so for how long a kidney infection can stop AF
