Early pregnancy testing

Ok, like everyone else I’m very impatient with testing for pregnancy. I’m 4 days from AF. I tested at 6 days with Early Response (a very fast negative). I’m assuming it’s common to show a negative and it being too early. Should I be talked off the metaphorical ledge of testing again at 4 days?! Is 4 days still too far? Also I realize I’m setting a bad habit for myself.
