An emergency contraceptive pill contains a high dose of levonorgestrel, which is very similar to progesterone, a naturally occurring hormone.
This high dose stops an ovary from releasing an egg (ovulation). Without a released egg, there is nothing for sperm to fertilize.
The high dose triggers the shedding of the uterine lining, That is what you see when you have withdrawal or breakthrough bleeding.
There would not be a risk for becoming pregnant by having unprotected sex two days after your period ended because it would be too early for ovulation.
