There are different forms of EC. Emergency contraceptive pills (ECPs), sometimes simply referred to as emergency contraceptives (ECs), or the morning-after pill, are medications intended to disrupt or delay ovulation or fertilization, which are necessary for pregnancy.[3][4][5]
Intrauterine devices (IUDs) ā usually used as a primary contraceptive method ā are sometimes used as the most effective form of emergency contraception.[4][6] However, the use of IUDs for emergency contraception is relatively rare.[1]
