Faint lines noticed next day...

So I may see a faint line on one or both of my two tests and I didn't really seem to notice them when I first checked but it could have been due to the lighting in the bathroom. I didn't notice them until the next day but I know you aren't supposed to check for results after 5 minutes. So am I just crazy orrr? Like either way it's faint but I am trying to not get too excited. I plan to test again in a few more days possibly a week. Any thoughts?
