What is emergency contraception
It is a method of contraception that can be used after intercourse took place, is called post-coital contraception, contraceptive pills used 10-15 years ago called contraception "second day" (morning-after pill).

Works primarily by blocking ovulation and / or other mechanisms that prevent implantation (tubal motility change, modify reactivity endometrium). Do not interrupt the evolution of pregnancy appear.

Method is less effective than other commonly used contraceptive methods. It should not be used regularly over other methods.

It seems that prevents the% of tasks that would have occurred without the use of method (average risk of developing pregnancy after unprotected sex is 8%, after using emergency contraception that risk drops to 2%).

Efficiency is even greater, as the method is used soon after unprotected sex.

If the method fails and the woman becomes pregnant after using emergency contraception, she may decide to keep the pregnancy.
What is emergency contraception
Any woman can use emergency contraception, provided not already pregnant.

If she wishes, may start using a contraceptive method immediately after taking emergency contraception, eg condoms or spermicides, or avoid sexual contact until you start to use the method you prefer (eg contraceptive pill or injection, it is better to wait for the arrival of menstruation, thus excluding a possible pregnancy, deriving from the failure of emergency contraception).

If using an IUD for emergency contraception, it can be kept as future method of contraception if a woman wants and no identifiable risk of STIs.

Emergency contraception does not protect against STIs (if IUD, this risk can be even increased).
