There are two types of contraceptive pills:

• the combined oral contraceptive pill (the pill)

• the progestogen-only pill (sometimes called the 'mini-pill' or POP).

  You take either kind once a day.

  Both are very effective in preventing pregnancy if taken properly, but they will not protect you against STIs or HIV. 

  It's a good idea that both partners have an STI test before having unprotected sex (sex without a condom), even if you (or your partner) are taking contraceptive pills.

The combined pill works by:

• stopping the ovaries from releasing an egg.
• changing the lining of the uterus so a fertilised egg cannot grow.
• making the mucous in the cervix thicker so sperm cannot get through.

Things to keep in mind:

• The combined pill usually makes periods regular and less painful.
• Contains the hormones oestrogen and progestogen
• You can choose to skip bleeds.
• Can cause side effects such as nausea or mood swings.
• If you have had or are at risk of blood clots, heart disease or get migraines, you may not be able to use the pill.
• You need to remember to take the combined pill every day, ideally at the same time.
