Bad batch of Pregmate

Ok so I’m like very obviously pregnant (yay!!!😭😭😭). I’ve take almost every test possible and they all are clearly pregnant and getting darker EXCEPT for Pregmate. The lines are like non existent (side 2)

I’m assuming that with symptoms and lines getting darker on other brands that it’s just a bad batch of tests? I purchased it from target, so any other TTC ladies I guess just beware, and use a few other brands to compare.
