clinical guard strips?

AW • Wife. Mom of 2 💗💙.
Does anyone find they always show a very faint test line? I am very early on but took one this morning just to test them out and it showed a faint line when inverted. I had that in September too (could have been a chemical but not sure). I can see the top of the line starting, it's barely there but still - with Wondfo I never saw this...
