Combined pill

The combined pill is usually just called the pill. It contains two hormones - an oestrogen and a progestogen.
These are similar to the natural hormones women produce in their ovaries. There are a variety of types of combined pill.

How effective is the pill?

How effective any contraceptive is depends on how old you are, how often you have sex and whether you follow the instructions.

If 100 sexually active women don't use any contraception, 80 to 90 will become pregnant in a year.

If the pill is taken according to instructions it is over 99% effective. This means that less than one woman in 100 will get pregnant in a year. If the pill is not taken according to instructions, more women will become pregnant.

How does the pill work?

The main way the pill works is:

It stops your ovaries releasing an egg each month (ovulation). It also:
Thickens the mucus from your cervix. This makes it difficult for sperm to move through it and reach an egg.
Makes the lining of your womb thinner so it is less likely to accept a fertilised egg.

Where can I get the pill?

Family planning doctors, nurses and most GPs provide contraception. You can go to any other GP if you prefer not to see your own doctor. fpa Helpline 0845 122 8690 9am to 6pm, Monday to Friday.
