Faint line and need a reality check

Tr

I am kicking myself so hard right now. I tested this morning but got interrupted before the test could develop. I didn't get to read it within time frame. When I came back to throw the test away 20 minutes later, there was a faint but discernable second line. I know that means I shouldn't consider the results valid, but - that said - I've also never had an evap or indent in my four years of using these particular tests (easy at home). Yesterday's test was stark negative and still is 24 hours later.

I'll wait as long as I can and retest, but in the meantime....ugh. I'm so annoyed for creating this stress for myself.
