Placebo pills? What are they, and am I safe?

Tomorrow is my last sugar pill, I should stop my period Sunday with my first hormonal pill.
Am I safe starting Sunday or do I have to wait another week like when I first changed to the pills?
(I used to be on nuva ring and i would always wait a week after starting a new ring but pills are different... And my gyno doesn't really speak English and doesn't explain much to me at all)
