Whats the likelihood?

I KNOOOOW it’s invalid BUUT. An hour after test was taken and in the sunlight, it’s super pink.

Would it only do this if I was pregnant ?

NOT getting my hopes up, I’m genuinely interested in how these work to get the hcg if you’re not pregnant!

OBVIOUSLY I’m going to retest in a couple days??

I’ve always heard evaps are thin, colourless lines

The reason for posting was to ask what the likelihood is.
