How many of you have received indent/evap lines AT or before the 3 minute mark. I never read the test after the 3 minutes so that I don't start seeing things.

But here and there I notice women posting pictures of their tests saying "before 3 minute mark" And the line will look VERY faint like grey-ish in color. and they'll turn out to be pregnant later. And then some women, same thing, 3 minute mark, grey-ish line, and it ends up being an indent.

So question... is this a common occurrence? I know to minimize this disappointment you shouldn't be testing when it's too early BUT we all do it sooo.. have any of you gotten the grey line and what was the outcome?
