Hello meli,
You have upset the normal hormonal balance that regulates your menstrual cycle. Plan B contains levonorgestrel, which is the same ingredient found in most birth control pills, but at a much higher dose.
It works by preventing or delaying ovulation and by interfering with fertilization of a released egg.
It may take one to two months before your cycle returns to normal. Please do not take Plan B for a while. Strongly consider using birth control, not emergency contraceptive to prevent pregnancy.
