Positive test or evaporation line?

I took a test yesterday and after a few min it was negative and I didn’t look at it again. Well after seeing some pictures of faint lines I went back and looked at it today and wondered if I was looking at it good enough and sure enough there is a line but now I’m wondering if it’s a faint line or evaporation line. My other two tests I have taken don’t have one... wouldn’t they if this one did? I don’t know if I should take another test or not. I had possible implantation bleeding last week and I am late. Also peeing a lot and tired and taking naps a lot
