"first response"

Why does this pregnancy test who boasts to kick the other brand's butt ONLY allow me to take the test 5 days before my period? that is a response I want NOW. Not first response... NOW RESPONSE.
I have to wait until Tuesday at the earliest... apparently.

sidenote: God bless my dear friend Jess who bought it for me as my first "baby gift". She is without a doubt a wonderful, caring, practical friend and I love her.
