Question: how long does it take to get your period on sugar pills?
Answer: The day after you take your last sugar pill, you start a new pack of pills. If you have a 21-day pack, you will take one pill with hormones every day at the same time for 21 days (week 1-3). Then for the next 7 days (week 4) you will not take any pills. You can expect your period sometime during this hormone-free week.
