Faint positive line gone?

[Cec19]

Hi, Im due on in a few days and felt the need to take a test as im feeling abit off. Within a minute a faint but obvious line came up but 10 minutes later it starts to fade then pretty much dissapears. What does this mean is it just a dodgy test?

Sometimes a line can appear while the test is developing and doesn’t mean a positive. Make sure you are using fmu and an early pink dye test. The boots own early ones are good. Avoid clearblue as they’re bad for false positives
