Dollar store tests?


Has anyone had a negative dollar store test? I took one on Friday and got a super faint line. Did another same thing... barley even noticeable. So I took a clear blue test and got a positive. Still light but now it wasn’t in question. Well today I bought another test to just see how dark it would be and yet again, barley anything. Wth!!! AF was due on Saturday and sure enough, it didn’t come. Which I figured since I got a positive test. But now this dollar store test thing is really stressing me out. I’ve had no spotting only mild cramping
