Risk ways towards Contraceptive?

Doctor how can I protect my self from getting pregnant?
 
There are many methods for avoiding pregnancy, or achieving contraception. All these methods have different efficacies and failure rates. The only definitive method to avoid pregnancy is to avoid sexual intercourse. The other effective methods of contraception are using condoms, taking Oral Contraceptive Pills (OCP or Birth Control Pills), Injectable contraceptives, and Intra Uterine Devices. All these methods have almost equal efficacy in preventing pregnancy. Condoms have the additional advantage of preventing transmission of Sexually Transmitted Infections. _None_ of these methods have a 100% efficacy in preventing pregnancy.
