Anytime you have unprotected intercourse, there is the risk of pregnancy.
Emergency contraceptives help prevent pregnancy by delaying ovulation. When taken as soon as possible (or at least within 24-72 hours) after unprotected intercourse, they can be about 75% to 80% effective at preventing pregnancy.
ECPs are usually well tolerated by most women. Some common side effects can be nausea (this is lessened if taken with either food or an anti-emetic), fatigue, headache, breast tenderness and changes in periods.
