I took 2 dollar tree tests yesterday with afternoon urine and both were faint (I had one a bit darker, after holding urine for about 5 hours and a fainter one after 2 hours), but had a pink line for sure. Even DH and DD1 saw it.
This morning with FMU I took a First Response and stark white. What the heck? I tried to see what the sensitivity was for the 2 and it seems they should be around the same.
