Emergency Contraception

Emergency contraception helps prevent pregnancy after unprotected sex or if regular contraception has failed. It is a safe and effective option when taken as soon as possible after the event. In the UK, there are two main types: the emergency contraceptive pill (morning after pill) and the copper IUD.

How Emergency Contraception Works

Emergency contraception works by delaying ovulation or preventing fertilisation. It does not end a pregnancy and is not the same as an abortion. The pill is most effective when taken within 24 hours, and the copper IUD can be fitted up to 5 days after unprotected sex. Both are safe and commonly used in the UK.

What to Expect After Taking It

  • You may feel sick, tired or dizzy for a short time
  • You might get a headache or sore breasts
  • Your next period could come earlier or later than usual
  • Some spotting or light bleeding may happen
  • You may have mild stomach pain or cramps
  • If you vomit within 2 to 3 hours of taking the pill, you may need another dose
  • Take a pregnancy test if your period is over 7 days late or very light
  • See a doctor if you have unusual or severe stomach pain (could be a sign of ectopic pregnancy)

Using Emergency Contraception Safely

  • Take the pill as soon as possible after unprotected sex
  • Use a pregnancy test if your period is late or unusual
  • Speak to a doctor if you vomit shortly after taking the pill
  • Use condoms or another method until your next period
  • Do not rely on emergency contraception as your regular method
  • Talk to a nurse, doctor or pharmacist about longer-term contraception options
