Frer false positive?

Heather • wife & mommy of two

I took the FRER 2 days ago and got a faint line. Took a digital the next night and it said “not pregnant”. So this morning I take a cheap little 88 cent test with my second morning urine and it was negative. Idk what to do! AF is a week late. My doctor won’t do a blood test until I’m 2 weeks late. Could this be a false positive? The line is deff pink.
