Be sure to read the patient information pamphlet that came with your Plan B, as it should explain that a side effect is "breakthrough bleeding" or "withdrawal bleeding", as this is most likely what you experienced after taking Plan B (not another period). Plan B would not cause you to have another menstrual period, but it does cause some "breakthrough bleeding" (which is just bleeding in-between periods).
You would expect your next period between 21-35 days after your previous menstrual period (the one you had a few days before you had sex).
What Plan B also does is cause a delay in your period (I know, not the best side effect!), but it usually is only a week late or early.

Does this help answer your question?
