Confusion/Pregmate Test

Hey ladies!

So 2 days ago I got a faint line on a Walmart cheapie with afternoon urine, I posted here & everyone said positive! Yesterday I tested with another Walmart cheapie & a Pregmate Midstream with the same cup of fmu. Both tests came out negative, but around the 3mm mark the Pregmate was faint. Today I tested with a Pregmate Midstream with my fmu & I got a faint line (I think) at the 2mm.

Now, the Pregmate instructions say after the 3mm the test is invalid. So I would love to know if anyone has experienced the Pregmate Midstream tests, I kept seeing good things (and I loved their opk tests I’ve used all month) but I’m worried this type of test is either not as good as their strips, or if I’ve got a bad batch, or maybe I’m just crazy & I really am pregnant. I’m just worried that even my 2mm line is false.
