12dpo ovulation need some device

Charlene • 1 👼🏻angel 1👶 baby girl and pregnant 🤰 with baby number 2

Hey ladies so I’m suppose to be 12dpo

Now I have a faint line on one test and looks negative on another. I’m currently having some spotting at the moment, but nothing like when af comes. I miscarried nearly two months ago so this is our first month ttc. Could the faint be wrong or the cheapie be wrong? Pictures to show

What do you guys think?
