Family Planning Plus

You should have a period or bleeding within 2-3 weeks after taking the emergency contraceptive. The ECPs gives your body a dose of

progesterone, which is one of the hormones that helps regulate your menstrual cycle. Progesterone is also one of the hormones found in

regular birth control pills.  ECPs help prevent pregnancy by delaying ovulation. Due to this, you may experience some irregular bleeding or spotting

throughout the next month. Your next period may be earlier or later than usual, and it may be lighter, spottier or heavier than usual.  Your cycle should return to normal

within the next month or so. If you do not have a period with 3-4 weeks after the ECPs, take a pregnancy test.
