First thing first, what is an Emergency Pill? It is a form of contraceptive taken to prevent pregnancy or conception after an unprotected sex.
The very common ones among few are: Postinor-1 or 2, Postpill or PlanB One Stop; its chemical constituent is Levonogestrel 0.75 or 1.5mg while combined pill contains ethinyl estradiol 0.03 with levonogestrel 0.15 which is commonly referred to as Combination-3 or Everyday Pill.
How does an Emergency Pill prevent pregnancy?

Conception is a process where an egg is fertilized by a sperm. An Emergency Pill acts by delaying the release of egg from ovary into the fallopian tube where a sperm is potentially waiting to meet with the released egg and when an egg is not released, conception cannot take place.
It also acts by preventing implantation of fertilized egg. How does it do this? It makes the uterine wall (endometrium) unreceptive to the fertilized egg. Reason Emergency Pill has up to 95% efficacy.
