Hook effect

I guess the hook effect is a real thing, I posted early this morning freaking out because my first response test that I took with fmu today was lighter than the test I took in the afternoon on Saturday. Well I took another just about an hour ago with diluted urine, I had drank coffee before and only held it about 45 min, and wa-la! The test line is darker than the control again. I think I’m going to stop testing though, this morning was too much stress to just turn out to be nothing

Bottom pic is with diluted urine, top is with FMU
