Contraception is a topic of great interest to couples who are sexually active but have no plan yet of bringing up a child. Although there is a wealth of information on birth control available online, there are about 1 million cases of unplanned pregnancy every year.
Many couples use birth control methods such as using a condom, calendar method or withdrawal method; these methods are not foolproof. There could be misuse of breaking of condom, unrecognized expulsion of an intrauterine device, or errors in calculation of period allowed in calendar method and it can lead to unplanned pregnancy.
While most contraceptive methods are used before and during sex, some methods can also be used soon after unprotected sex. Although they are known as the morning-after pill or the next day pill , the correct name is secondary contraception, postcoital contraception or emergency contraception because pills are not the only means used in emergency contraception.
Since the implantation of the egg (ovum fertilized by the sperm) in the womb is achieved only after about 6 days after fertilization , this time allows the use of contraception to avoid pregnancy. Emergency contraception includes emergency contraceptive methods such as IUDs and morning after pills.

Although abortion is a preferable alternative and much less traumatic, emergency contraception must remain a method to be used occasionally and not routinely. To prevent unwanted pregnancies it is recommended to use long-term contraceptive methods.
