AF due today...

Miss AF is due today. Usually she comes a few hours after I wake up on the day she's due. So far, nothing. The last 2 cycles glow has been spot on on when she's supposed to be here.... we shall see what happens. I'm so afraid to test because I usually test then AF comes a few days later... debating on whether to go ahead and test if she doesn't come today or just wait a few more days...
