WHAT IS GOING ON!?

Catrina

A few days ago I took 3 to 4 first response test had a faint line along with a digital that said “Not Pregnant”. So I took another first response test yesterday morning, the line became darker. I also took another digital that says “Not Pregnant”. Well I just started bleeding this morning it’s not really spotting( feels like a normal period) I’m confused to what’s happening!
