You can also go to your doctor and say you want the pill that doesn't take a week off for your period. For a long time, women skipped the placebos without telling their doctors. Eventually, studies were done to satisfy them that nothing bad would happen if we never menstruate. So, they now make the pill in packs of 30, with no placebos.
Doing this will save time in terms of getting refills, as you're not short by seven pills every month.
