The 'Pill', or Oral Contraceptive Pill (OCP), is a popular way that women chose to protect themselves against unwanted pregnancy. It's a very reliable birth control method, but it does not protect a woman against sexually transmitted infections (STIs).
You get it on a doctor's prescription.
There are two main types of oral contraceptive. The first, often called 'the Pill', has two types of hormones in it - oestrogen and progestogen. The second (often known as the POP or Mini-Pill) has only progestogen in it and can be used for contraception when women are breastfeeding.
The Pill - combined oral contraceptive
The combined oral contraceptive pills contain two artificial hormones, oestrogen and progestogen. They work by:
- stopping the ovum (egg) being released each month
- changing the lining of the womb so that a fertilised egg can't implant and grow
- making the mucus (sticky fluid) at the cervix thick, so that it stops the sperm getting through to the ovum.
For more information have a look at the SHine SA fact sheet The Pill (combined oral contraceptive pill).

Progestogen-Only Pill (POP, or mini-Pill)
The POP has one hormone in it, progestogen.
The progestogen-only pill works by
- making the mucus (sticky fluid) at the entrance of the uterus thicker so that sperm can't get through
- changing the lining of the uterus so a fertilised egg can't grow
- sometimes stopping the release of an egg by the ovary
The POP can be safely used by women who are breastfeeding or who can't take the regular pill for medical reasons. The POP does not interfere with milk supply. Research has shown that the amount of hormone that might pass through the breast milk is extremely low, and will not harm the baby.
