Important
Medical or family history, as well as certain lifestyle factors, might mean the pill isn’t suitable for some people.

How the pill works

The combined pill works to prevent pregnancy in three ways:

  1. It stops eggs being released from the ovaries (ovulation)
  2. It makes it harder for the sperm to reach the egg
  3. It makes the uterus (or womb) lining thinner so a fertilised egg cannot implant

Periods and the pill

During your pill-free week, or when you are taking the placebo (dummy) pills, you may get a bleed. This isn’t a proper period, but is called a ‘withdrawal bleed’ and is caused by not taking hormones during this week. This can happen at any point during this week, and you should start your next pack on time whether or not you are still bleeding.

There is also no harm in taking the pill back-to-back to avoid getting a withdrawal bleed. More about how to take the pill

You may experience bleeding when you first start taking the pill. This is very common, isn’t usually anything to worry about and should settle down within three months. If you are worried, talk to a doctor or nurse for advice.

How to get the pill

As of December 2023, you may also be able to get the pill from a pharmacy without needing to see a doctor or nurse. You will need to have a consultation with a pharmacist before you can be prescribed the pill.

The combined pill is available free of charge from a range of services including contraceptive clinics, your GP, Brook and some pharmacies.

Contraception and sexual health services such as Brook are free and confidential, including for people under the age of 16. Health professionals work to strict guidelines and won’t tell anyone else about your visit unless they believe you’re at serious risk of immediate harm. Find out more about Brook’s confidentiality policy.

At the appointment

Before you can start on the combined pill you will usually be assessed by a nurse, doctor or in some cases a pharmacist. An appointment will typically include:

  • A few questions about your medical and family history to work out what would suit you best
  • You’ll discuss other medicines you are taking in case they make the combined pill less effective
  • The doctor or nurse will take your blood pressure and weigh you

When you first start the combined pill you will usually be given a three month supply. Follow up appointments and reviews are then usually every 6-12 months providing there are no issues. You can return to the clinic at any time if you are worried about anything.

You will not be required to have an internal or breast examination for the combined pill.

When to start the pill

If you start taking the combined pill in the first five days of your period, you will be protected against pregnancy straight away.

If you have a short menstrual cycle, where your period is normally 23 days or less, you will need to start taking the pill in the first four days to be immediately protected (because you might ovulate early).

If you start the pill at any other time in your menstrual cycle you will need to use additional contraception, such as condoms, for the first seven pill taking days.

This information does not apply to the combined pill Qlaira. If you use this pill you should contact a doctor or nurse if you are not sure how to take it or read the manufacturer’s instructions.

Starting on the combined pill after pregnancy

It’s possible to start on the combined pill after giving birth, a miscarriage or abortion but when it is safe to start on this method does vary.

After giving birth

You can become pregnant from as little as three weeks after giving birth.
If you are not breastfeeding, it’s likely you can start the pill on day 21 after the birth (check with a doctor). If you start after week three (21 days), you will need to use alternative contraception for the first seven days.
If you are breastfeeding, you’re not advised to take the combined pill until six weeks after the birth. After six weeks it is safe to do so.

After an abortion or miscarriage

You can become pregnant from two weeks after an abortion or miscarriage.
If you start on the pill within five days of the abortion or miscarriage you are protected from pregnancy straight away
Any later than day five and you will need to use additional contraception for the first seven days.

Always speak to your midwife, GP or nurse at a sexual health clinic to check this is the right method for you

How to take the pill

How to take the combined pill:

  • Choose the time of day that suits you best and take it at the same time every day until you finish the packet (this will help you remember and get into the habit of taking it)
  • New guidelines (2019) confirm that there is no harm in taking the pill continuously without a seven day break. This means you are unlikely to have a withdrawal bleed. It’s a good idea to speak to your doctor or nurse to see what is right for you

Although there are many different brands of pill, there are three main types:

Monophasic 21-day pills
  • Each pill has the same amount of hormone
  • You take one pill every day for 21 days, and then have a seven day break, if you wish (see 2019 guidelines)
  • You then start the next pack of pills.
  • Microgynon, Brevinor and Cilest are examples of this type of pill.
Plasic 21-day pills
  • Contains two or three sections of different coloured pills in a pack
  • Each of these sections has a different amount of hormones
  • You take one pill every day for 21 days
  • Then you have a seven day break before starting the next pack, if you wish (see 2019 guidelines).
  • It is really important that you take phasic pills in the right order.
  • Binovum and Logynon are examples of this type of pill.
Every day (ED) pills
  • Packs contain 21 active pills, and seven placebo (dummy) pills which look different
  • This means you take 28 pills in total with no break
  • It is really important that you take the pills in the right order.
  • Microgynon ED and Logynon ED are examples of this type of pill.

Always follow the instructions that come with the packet, paying careful attention to which medicines and antibiotics might affect it.

Factors impacting its effectiveness
• Taking it more than 24 hours late
• Vomiting within two hours of taking it
• Very severe diarrhoea that lasts for more than 24 hours
• Some medicines such as those used to treat epilepsy, HIV and TB and the complementary medicine St John’s Wort (If you are prescribed medication always say you are taking the combined pill)
• Antibiotics used to treat STIs and antidepressants (Commonly used antibiotics do not reduce the effectiveness of the pill, but it is always best to check with the doctor, nurse or pharmacist first)

Talk to a pharmacist, doctor or nurse and use additional contraception such as condoms until you know for sure your contraception is working to protect you from pregnancy.

What to do if I miss a pill (or more)

One missed pill

If you have missed one pill, or if you have started the new pack one day late:

  • Take the last pill you missed now (this might mean taking 2 in one day)
  • Continue taking the rest of the pack as usual
  • Emergency contraception or additional contraception is not usually required but may need to be considered if pills have been missed earlier in the pack or in the last week of the previous pack
Two or more missed pills

If you have missed two or more pills or if you have started the new pack two or more days late:

  • Take the last pill you missed now (this might mean taking 2 in one day)
  • Continue taking the rest of the pack as usual
  • Leave any earlier missed pills
  • Use an additional method of contraception for the next seven days
  • If you have had unprotected sex in the previous seven days, you may need emergency contraception
If seven or more pills are left in the pack after the missed pill
  • Finish the pack
  • Have the usual seven day break or take the placebo tablets
If fewer than seven pills are left in the pack after the missed pill

Finish the pack and begin a new one the next day (this means missing out the break or not taking the placebo tablets)

This information does not apply to the combined pill Qlaira. If you use this pill you should contact a doctor or nurse if you are not sure how to take it or read the manufacturer’s instructions.

Coming off the pill

How quickly it leaves your system:
The hormones from the pill will usually leave your body within a couple of days – no matter how long you have been taking the pill for.
How quickly you can get pregnant:
This varies depending on when ovulation (releasing an egg) starts up again. It could be a matter of days or months depending on the person. Fertility levels should return quite rapidly, so use condoms or another method if you don’t want to get pregnant.
What happens to your periods:
Talk to a doctor or nurse if after stopping the pill you have irregular periods or it’s taking a long time for your periods to start again.
What physical changes there might be:
Everyone reacts slightly differently to coming off the pill. This is often temporary as your hormone levels self-regulate over the course of a few weeks or months. If symptoms persist or worsen please see your doctor or nurse for help and advice.

FAQs

Will the pill make me gain weight?

There is no evidence of weight gain with the combined pill.

Will the pill lower my libido (sex drive)?

Different contraceptive methods affect people differently. It is possible that contraception may increase or decrease your libido.

If this happens and you don’t like it, you can always stop and try another method. It’s all about finding the method that works for you.

For some, being on contraception in itself helps increase their libido as they have reduced anxiety around having sex knowing that they are protected from pregnancy.

What if I start on the pill and don’t like it?

You may experience some side effects of taking the pill in the first couple of months but these tend to be short-term. This is why, if you can, it’s best to trial a contraception method for at least three months before deciding it’s not for you.

There are different types of combined pill so you might find that another type of combined pill will suit you better. It’s a good idea to talk to a medical professional to discuss your options.
