THAT TWO WEEK WAIT!

I guess I am what you call a pee on a stick addict lol. I want to know how you guys get thru your two week wait!?! AF according to the glow calender is due on the 24 which would be a 30 day cycle. Tho I have always been 28 days like clock work, but I'm assuming because I ovulated on CD 16 (7/9/15) that's why it pushed it later. Has anyone else had this problem? Do you trust your Glow calender? Does it adjust to your cycle the longer you use it instead of making guesstimates?
