The Pill

What is it?

It's a tablet taken by women for one of two reasons:

So that she doesn't get pregnant. It is the most popular form of contraception in the UK.

So that her periods are less troublesome (lighter, less PMS, more predictable). So women who are not having sex also use the Pill.

There are two main types:

The combined pill (containing two hormones: oestrogen and progestogen)

This is more effective contraception. And makes our periods regular and light. We usually take it for 21 days then have 7 days off (but not all pills are the same - follow your instructions)

The mini-pill (or progestogen-only pill).

This is slightly less effective. And doesn't make our periods easier. In fact, it can make them unreliable or absent altogether. It is usually taken by women who can't take the combined pill for medical reasons. We take it at the same time every day, with no break.

How does it work?

The pill may prevent pregnancy in three ways:

• By stopping ovaries releasing eggs (ovulation).
• Thickening vaginal fluids so sperm can't get into our womb
• And making the womb slippery so eggs can't stick to it.

How do you get it?

If you think you might want to go on the Pill, see your GP or Family Planning Clinic who'll talk you through it. If you decide to go ahead they'll prescribe the best Pill for you. Remember, all contraception is free.

Does it have any side effects?

Women on the combined pill have easier periods: more regular and lighter, too. Often they also have less period pain and PMS. Some types can clear up spots.

Some women put on a little weight. It may be possible to switch to a different Pill if this happens.

Research also suggests that the combined Pill protects against ovarian and womb cancer, but slightly increases the risk of breast cancer. It also increases your chances of getting a blood clot. Your doctor will talk you through the pros and cons.

But remember - it's the most reliable form of contraception (after not having sex at all!) And always much safer for your body than getting pregnant.

Does the Pill always work?

When used properly, the Pill is over 99% effective. This means that of 100 women using the combined pill every year, only one will get pregnant.

However, it might not work if the woman misses pills out, doesn't take them at the same time each day or gets sickness or diarrhoea.

Ask your GP or family planning clinic to explain what to do if this happens.

REMEMBER: It's against the law in the UK to have sex if you're under 16. For more information see the Age of Consent factfile.
