I swear I saw a faint line... I took the test (first response) apart, to see if a plain white background would help better than the plastic housing... I've never seen a pink line on the pee strip part before. I'll test again tomorrow. I just find it odd, 3 faint blue dye positives (almost look like evap lines, but they showed up within the 10 minutes). To a, what appears negative pink dye? My previous two showed up on blue dye instantly and were correct...
