i-pill can work in any of three different ways depending on where you may be in your menstrual cycle.

• It may stop an egg being released from the ovary.
• If an egg has been released, i-pill may prevent the sperm from fertilizing it.
• If the egg is already fertilized, it may prevent it from attaching itself to the lining of the womb.

It is important to note that pregnancy is established only after the fertilized egg attaches itself to the womb.

i-pill is ineffective if the pregnancy is established (i.e. the fertilized egg has attached itself to the womb). It is therefore not an abortion pill.
