Side Effects Sometimes, emergency contraception can change the length of your monthly menstrual cycle, making your next period come as much as a week earlier or a week later than usual. Some women also find that the hormones in the pills can cause unexpected bleeding, but this is not a common or serious side effect.

“When taken soon after intercourse," Dr. Huldeen explains, “it can prevent an egg from ever being released. It does not make you abort.” The morning-after pill may also delay ovulation, stop an egg from becoming fertilized, or keep a fertilized egg from becoming implanted, depending on your menstrual cycle.

When you take the morning after pill, the hormone it contains prevents you getting pregnant. It does so by thickening the mucus at the entrance to the womb (so that sperm can't get to the egg), altering the lining of your womb (so an egg can't implant) and by preventing ovulation.
