Pregmate evap

Won’t post the pic since the group doesn’t allow it, but anyone else get evaps on pregmate lately? Took a couple the last few days with no evap. Today I took one, was negative within the window. Thought MAYBE I saw a vfl but couldn’t be sure so I counted it negative. Then later I looked at it (as I always do even though ***I know it’s invalid****) and it had a faint line. Yes I know it’s technically invalid and an evap but like dang. Why?😫

I usually use easy @ home but I was out and got pregmate at target. Easy @ home has never given me evaps before. The strips at least. I did get a faint false positive on their sticks but have never gotten a false result on their cheapie strips.
