Faint line// can someone tweak this?

Hey everyone. I miscarried about eight weeks ago and I am wondering if I am going crazy or if there is a faint line on this test. I took three others that look the same. Also I am having symptoms of pregnancy but not sure if it's that or an iud I got put in a few days ago. They checked for pregnancy before putting it in and it was negative. In my experience of being pregnant, a pos can show up out of nowhere because that's what happened to me.
