Miscarriage/non viable pregnancy and HCG tests.....

If you had a miscarriage or a pregnancy that wasn’t viable etc, would your HCG tests get lighter, not darken or become negative?

Is testing daily and seeing a darkening line reassuring or is it not really an indication that a pregnancy is ‘safe’?
