Faint "not pregnant" lines

Ka

Hey has anyone else noticed this? When I take the tests with the two lines the "pregnant" line shows up immediately and bold!! But the "not pregnant" line is faint... I've never seen any post about those lines being faint??

My first pregnancy was a chemical pregnancy 😭 this is my second time ever seeing "pregnant" I'm so nervous and excited. We've wanted this for so long now! Doctors appointment is set for Oct 1st!
