If you’ve had unprotected sex or your usual contraception has failed, emergency contraception can help reduce the chance of pregnancy. It works by delaying or preventing the release of an egg, meaning fertilisation is much less likely. It is not an abortion and will not affect an existing pregnancy.
According to the NHS, the morning-after pill can be up to 95% effective if taken at the right time. In this blog, we will explore how emergency contraception works, the options available, and when you should take it.
Emergency Contraception: How It Works
Emergency contraception works by preventing or delaying the release of an egg from the ovary. If no egg is released, sperm cannot fertilise it. Some methods may also make it more difficult for sperm to reach the egg.
It is important to remember that emergency contraception does not protect against sexually transmitted infections. For that, you will need barrier protection such as condoms.
Types of Emergency Contraception
There are two main types of emergency contraception available in the UK:
- Emergency contraceptive pill (morning after pill): Levonorgestrel or ulipristal acetate tablets.
- Copper intrauterine device (IUD): A small device placed into the womb by a trained professional.
Both options are effective, but the IUD is the most reliable form of emergency contraception, as it can prevent pregnancy even if ovulation has already happened.
When to take emergency contraceptive pills
The timing of the morning-after pill is very important. Levonorgestrel is most effective when taken within 72 hours of unprotected sex, while ulipristal acetate can be taken up to 120 hours after.
The sooner you take it, the higher the chance of preventing pregnancy. This is why morning-after pill timing should be considered carefully.
Understanding Emergency Contraception Effectiveness
Emergency contraception effectiveness depends on the method chosen and how quickly it is used.
- Levonorgestrel pill: Works best within 24 hours but can be used up to 3 days after.
- Ulipristal acetate pill: Can be effective for up to 5 days.
- Copper IUD: Over 99% effective and can be fitted up to 5 days after unprotected sex.
Your health, medicines you may be taking, and how close you are to ovulation can all affect how well the pills work.
How to Decide Which Option Is Right for You
Choosing between emergency contraceptive pills and the IUD depends on timing, personal health, and preference. If you want the most effective long-term option, the copper IUD also provides regular contraception once fitted.
