Anyone get a false Negative Early PT?

So I've been experiencin EXTREME FATIGUE (when I say EXTREME I mean I sleep 8 hours at night & nap an extra 5 between classes) sensitivity to smells and cramping + mood swings since my last period consistently, so I started to think maybe I was pregnant. I logged my symptoms and Glow told me to test yesterday so today I took an early pregnancy test (mind you, it was from the dollar store I was in there and figured it was worth a shot) and it came back negative. Should I retest if I don't get my period? It's due tomorrow. Really hoping it was false 😪
