Freaking evaporation line. Tricks me every time. Is it a gray or colorless, faintly indented line? Or is it in fact eeeeever so slightly PINK and therefore valid?
And of course, given the ridiculous, dumpster diving, am I or aren't I debacle of trying to determine whether or not I was pregnant with Eli, I can never leave a test alone after the ten minute window because I know now that SOMETIMES, at least with my particular hormone-challenged body, a genuine positive decides to take its sweet time emerging. Like, HOURS of sweet time.
Musta really been hard in the olden days, when the only pregnancy confirmation was the realization that you were barfing up your griddle cakes from the back of the covered wagon every morning and that fancy, go-to-town girdle just wasn't lacing up anymore. Or in some cases, I'm sure, when an actual HEAD was emerging from your body. That would be pretty definite.
