Clear blue, positive or evaporation line?

[hellopandas]

This is the first test i did, and it came up with this. i'm not sure if it's positive or evaporation. i've had two negative tests after this

It’s just invalid. It needs to be a full complete line to be positive, if the others were both negative then retest in a couple of days. Good luck.

Invalid yesterday unfortunately as the line is broken
