Periods on pill: Your periods will now be during the last week of pills in the pack if you have a 28 day pack, or after you finish the pack if using a 21 day pack. However, all of this could be thrown out the window by using Plan B in the midst of all of this. It's not a great idea to mix plan B and the pill. If you want to be extra safe and don't trust the pill alone, use a second contraceptive like a condom.
