I took this first response test a few days ago, and I could have sworn I saw a line when I first took it. I kept it and went back and looked at it just now and now there’s a darker line. I know this is usually considered an evap, but with it being that I thought I saw one when I took it what do y’all think? It was taken with fmu. The bottom pic is when I first took it.
