Helpppppp

So I took a digital pregnancy test that literally says “not pregnant”. But I’ve always heard the dollar store ones are the best. Im like SUPER late on my period. Like 10-15 days late. But I took the test & it came back not pregnant. I have sore boobs, cravings, & I’ve been super tired. I started spotting last week for like a few hours but only when I wiped, i didn’t have to wear anything. Should I take another test? I got pregnant in December & used 5 dollar store ones & they all came back super faint so I’m scared I’m just not super pregnant yet & the digital isn’t picking up.
