• Emergency contraception can be used to prevent pregnancy after you have had unprotected sex. So if you have had sex without using contraception or you think your contraception may have failed then it may not be too late to prevent pregnancy. Emergency contraception can be used up to 72 hours after unprotected sex, but the earlier it is taken the more likely it is to be effective.
• There are two types of emergency contraception, hormonal pills or the coil. The hormonal pills can either be prescribed by your GP or bought at the chemist. The coil can only be obtained via the Family Planning Clinic.

How do I use it?

• Take 2 pills immediately and 2 pills exactly 12 hours later. (NB. Depending on the type of pill prescribed or purchased). The second set of pills may make you feel sick. If you are actually sick within 2 hours of taking them they will not work. Discuss this with your doctor.

How does it work?

• It works by either stopping an egg from being released (ovulation) or by stopping a fertilised egg from implanting in the womb. This means that the pills prevent a potential pregnancy rather than end an existing one.

How do I know it has worked?

• Your next period will come earlier or on time. If it comes earlier it may last longer. Any delay in your next period means you could be pregnant and you should do a test and see your doctor.

Are there any risks?

• Emergency contraception is suitable for most women but if you have had a thrombosis (blood clot) or if you have a bad migraine at the time you need to take the emergency contraceptive pills you may not be able to take them and should consult your doctor.
• There is still a slight risk of an ectopic pregnancy, i.e. a pregnancy in the tubes instead of the womb. If you feel a bad pain in the lower stomach with little or no bleeding, it is important to see your doctor.

What next?

• It is very important to use a reliable method of contraception if you do not want to get pregnant.
• This method is for emergencies only.

The Coil

In an emergency you can prevent pregnancy by having a coil fitted in your womb by a doctor. It may stop an egg from implanting in the womb. It must be fitted by a doctor within 5 days of unprotected sex. The coil is not suitable for all women. Your GP, Practice Nurse or Family Planning clinic will be able to provide more information about this method.
