too early?

Kelsey
I think my period is due in 3 days but Glow says 5. I have been feeling REALLY off the last 3 days. I've been dizzy, not hungry at all, super emotional, my breasts itch (not hurt, but it's annoying) and I'm tired ALL THE TIME! My husband thinks I'm sick because I'm hot and cold at odd times.
All this to ask, is it too soon to test? I peed in a cup but haven't wanted to test, I just keep staring at it.
