Your period should arrive when you get to the white pills (after the 21 pink ones). I assume you know that not all woman will bleed from day 1 of the inactive pills or for the full 7 days.
Keep on taking the pills one after the other, the packs one after the other regardless of what your periods do. The new pill's hormones will force your cycle to adapt to it. You should never adjust your pills to fit your cycle.
Best of luck!
