I Want To Delay My Period. I Am Taking Elleste

I want to delay my period. I am taking Elleste duet 2mg. (16 orange estradiol tablets, then 12 white estradiol/norethisterone tablets.) does it make a difference whether I extend taking the orange or the white tablets to delay the bleed? A previous answer says to extend the white - it's just that my mood is much better on the orange!!
