Several faint lines & period symptoms

Okay ladies so I’ve had the same exact faint line appear on every test for the last 4 days, it hasn’t gotten darker or lighter, today the very top of my stomach hurts which I’ve never had before but I’m getting the slightest cramping on and off, with faint spotting. Should I start considering this might be a chemical pregnancy or can this be normal ?
