Dollar Store Assured HPT?

Karen
I am 12 DPO today and AF is due Friday (14 DPO). I ordered some FRERs but they won't get here til tomorrow so I caved and took a dollar tree Assured test this afternoon. I waited 3 hours from the last time I used the restroom (I know FMU or 4 hours is best) but I've been patient so far this TWW and just couldn't be patient anymore. Unfortunately though, there wasn't even a hint of a line. 
Do you think I'm out this month? Or is Assured not very sensitive? I know it's more accurate on the day of missed period. I have increased EWCM, cervix is soft today (yesterday was firm), and I just REALLY want it to happen! 
Anyone test negative with Assured when they were actually pregnant? Or am I just getting my hopes up??
