Emergency contraception can be used to prevent pregnancy if: no condom/ other birth control during sex, messed up on regular birth control (did not take a pill/changed patch/ no shot taken on time), condom broke/slipped after ejaculation, withdrawl failed, forced to have unprotected sex

Emergency contraception should not be relied on as a regular form of birth control because it does not work well and some emergency contraception have higher hormone levels

emergency contraception does not work if you are already pregnant 

Forms of emergency contraception: Copper-T (IUD) , ella, plan b
