Emergency contraceptive is contraceptive method that can be used by women in the first few days following unprotected intercourse to prevent unwanted pregnancy. The use of ECS can inhibit or delay ovulation while others have suggested that its use may impair endometrial receptivity to implantation of the fertilized zygote. There are four forms of ECS methods used as emergency contraceptives Levonorgestrol (LNG) only regimen 0.75 mcg LNG (or 1.5 mcg norgesterel) taken as soon as possible after unprotected sex about optimally within 72 h. There is no doubt that assisting women to achieve their reproductive intension will be best achieved by encouraging the adoption of routine family planning methods. Short of this mechanisms must be in place to assist women who, either because of method failure or discontinuation become at risk of unwanted pregnancy and with to do something about it, ECS remain the better safe way in lowering rates of maternal morbidity and mortality from unsafe abortion following on wanted pregnancy.
