A guide to what happens when you miss a contraceptive pill, when emergency contraception may be needed, and when to seek professional advice.
Does One Missed Pill Matter?
In many cases, missing a single contraceptive pill does not significantly reduce your protection against pregnancy. However, the impact depends on the type of pill you take, how late the pill is, and where you are in your pill pack.
Different contraceptive pills have different rules regarding missed doses — some have a longer window before protection is affected, while others require more careful timing. Because guidance varies between products, it is important to follow the instructions provided with your specific pill. If you are unsure whether your protection has been affected, a pharmacist can help assess your situation.
What to Do If You Miss One Pill
If you have missed one pill, the first thing to do is take it as soon as you remember. Many people panic when they realise they have forgotten a dose, but acting promptly often helps maintain protection.
- Take the missed pill as soon as possible
- Continue taking the remaining pills as normal
- Check the patient information leaflet for your specific medication
- Seek advice if you are unsure about what to do
Because recommendations differ between contraceptive pills, personalised advice is often the safest approach.
What to Do If You Miss Two or More Pills
Missing two or more pills can increase the risk of pregnancy, particularly if the missed pills occur at certain points in your pill pack. In some situations, additional contraception such as condoms may be recommended for a short period, and you may need to continue taking active pills in a specific way to restore protection.
Because the guidance can be complicated, it is important to seek advice if you have missed multiple pills. A pharmacist can review your circumstances and explain the most appropriate course of action.
When Emergency Contraception May Be Needed
In some situations, emergency contraception may be appropriate following missed contraceptive pills. Many people assume that emergency contraception is only needed after completely unprotected sex, but missed pills can sometimes increase pregnancy risk as well.
- You have missed multiple pills
- You have had unprotected sex
- Your contraceptive protection may have been reduced
- The missed pills occurred during a higher-risk part of your cycle
If you are unsure whether emergency contraception is necessary, it is best to seek advice as soon as possible. A pharmacist can assess your circumstances and discuss the available options where appropriate.
Missing Pills Due to Sickness or Diarrhoea
Even if you have taken your pill correctly, sickness or diarrhoea can sometimes affect how well it works — your body may not fully absorb the medication.
The advice varies depending on the type of pill you take and how long your symptoms last. If you have been unwell and are concerned about your contraception, it is worth speaking to a pharmacist for personalised guidance.
How to Reduce the Chance of Forgetting
Forgetting the occasional pill is common, but there are simple ways to make it less likely. If you find it difficult to remember your pill regularly, you may wish to discuss alternative contraceptive options with a healthcare professional — some methods require less frequent administration and may be easier to manage.
- Take your pill at the same time every day
- Set a phone reminder or alarm
- Use a medication reminder app
- Keep your pill pack somewhere visible
- Link it to a daily routine, such as brushing your teeth
When to Seek Professional Advice
Many situations can be assessed quickly by a pharmacist, helping you understand your options and avoid unnecessary worry. The sooner you seek advice, the more options may be available if further action is needed.
- You have missed multiple pills
- You are unsure whether you remain protected
- You have had unprotected sex after missing pills
- You have experienced vomiting or severe diarrhoea
- You are confused by the instructions in your pill leaflet
- You are concerned about the risk of pregnancy
