Which of the following are the common methods of emergency contraception?

Emergency contraceptive pills (morning-after pills) and an intrauterine device (IUD) are the common methods of emergency contraception. Condoms and spermicides cannot be used as emergency contraceptives. Condoms prevent pregnancy by physically blocking the entry of sperm into the vagina during sexual intercourse. They do not have any effect on sperm that have already entered the vagina or uterus. Spermicidal creams and jellies must be applied to the vagina before sexual intercourse. They are used in conjunction with barriers (e.g., condoms and diaphragms).
