Two lines?

How soon before a missed period did you ladies test? Was the line bright or faint? I’m suppose to get my Period in 4 days. I just tested and I swear I see two lines I try to take a picture but it don’t come out. Idk if it’s the fact we been trying for 4 months just wanting to see two lines that my eyes are lying to me! How bright was your line when first tested?
