Emergency contracept. So it is important to make sure there is no pregnancy after the emergency contaception dosage. It works by altering the ovulation timing therefore it alters the menstrual cycle leading to an i scheduled menses. If other hormonal methods of contraception are initiated, then they can help re-regulate the menstrual cycle.
