Line or wishful thinking?

I took a test this morning and was unsure that I did it right ( I am in unfamiliar territory with these!) i don’t think I had enough pee for this test. The next one is the one I posted where I dipped it in a pee cup like it suggested. I think I can see a very faint line, this was after 3 minutes. I’ve been having lots of hair loss, my teeth having been breaking which I heard is a thing too… my period was short and much lighter than normal.😕 any ideas?? Opinions??
