This is essentially the same text as a post I just did on my regular discussion forum:
I know I shouldn't be testing so much. I. Know. It. But I wanted comparisons for all 3 brands from yesterday. Then I was going to just maybe do one a day till Friday.
My Answer test from earlier this afternoon is ever so slightly lighter than yesterday's (the one I pictured). It's really almost identical, just a tiny hair lighter. I thought this was no big deal due to differences in dilution. In person it is very pink and very there.
BUT, something possessed me 2 hours later to do another FRER. It is a total BFN. No color, no line, no nothing. This morning's FRER was measurably darker than yesterday's. But this is as white as white can be.
Surely I should be able to see SOMETHING.
Is it now just over?
Why did I do this to myself?
Why can't anything be clear one day and clear again the next day?
