HPT this morning

Was freaking negative! 
According to glow, my period was originally supposed to be here on the 30th. Still nothin'. No spotting. Absolutely nothing. :/ and my periods have been pretty on point with the app. 
And since AF hasn't come, my fertile days have moved as well, which is confusing me even more. 
I'm beginning to get really sad and think that I'm just broken, and this trying to get pregnant thing is going to be a lot more difficult than I expected it to be. 
Any words of wisdom, or words of encouragement would be highly appreciated.
