Taking the emergency contraceptive pill has not been shown to cause any serious or long-term health problems. However, it can sometimes have side effects.
Common side effects include:
- abdominal (tummy) pain
- irregular menstrual bleeding (spotting or heavy bleeding) before your next period is due
- nausea (feeling sick)
- tiredness
Less common side effects include:
- breast tenderness
- dizziness
- headache
- vomiting (being sick) - seek medical advice if you vomit within three hours of taking the emergency contraceptive pill
Any side effects will normally pass quickly.
When to see a doctor or nurse
If you are concerned about any symptoms after taking the emergency contraceptive pill, contact your GP or speak to a nurse at a sexual health clinic.
You may also want to talk to a doctor or nurse if:
- you think you might be pregnant
- your next period is more than seven days late
- your period is shorter or lighter than usual
- you have any sudden or unusual pain in your lower abdomen (tummy)
