The combined pill is a popular contraceptive used by women worldwide, containing two hormones—oestrogen and progestogen—that work together to prevent pregnancy by stopping ovulation, thickening cervical mucus to block sperm, and thinning the uterine lining to reduce the chance of implantation. When taken correctly, it is over 99% effective. Beyond pregnancy prevention, it offers additional benefits like regulating periods, reducing menstrual pain, and helping with acne. The combined pill may not be suitable for everyone, particularly those with certain medical conditions like a history of blood clots or high blood pressure.
What is the combined pill?
The combined pill is an oral contraceptive containing synthetic estrogen and progestin that works to prevent pregnancy by stopping ovulation, thickening cervical mucus to block sperm, and thinning the uterine lining to prevent implantation. Taken daily, it’s over 99% effective. Besides preventing pregnancy, it can be used to help with painful periods, acne and conditions such as PMS and endometriosis.
How does the combined pill work?
The combined pill prevents pregnancy in three main ways:
- Stopping ovulation: The pill prevents the ovaries from releasing an egg, meaning there’s no egg to be fertilised by sperm.
- Thickening cervical mucus: The hormones in the pill cause the mucus around the cervix to thicken, making it difficult for sperm to swim through and reach an egg.
- Thinning the uterine lining: Even if an egg were fertilised, the thinning of the lining makes it harder for the egg to implant in the womb.
How to take the combined pill?
Typically, the combined pill is taken every day for 21 days, followed by a 7 day break, during which time you may experience a withdrawal bleed, similar to a period. Some women opt for continuous use, skipping the break and preventing withdrawal bleeds entirely. It’s important to take the pill at the same time each day for maximum effectiveness.
Advantages of the combined pill
- Highly effective – When taken correctly, the combined pill is over 99% effective at preventing pregnancy.
- Cycle regulation – It helps regulate menstrual cycles, reducing irregular periods.
- Reduces menstrual pain – Many women experience lighter and less painful periods.

Possible side effects
As with any medication, the combined pill can cause side effects, which may include:
- Headaches
- Nausea
- Breast tenderness
- Mood changes
- Spotting between periods
These side effects usually subside after the first few months, but if they persist, it’s a good idea to consult your doctor to discuss other contraceptive options.
Is the combined pill right for you?
Not everyone is suited to take the combined pill. Women who smoke, have a history of blood clots, or suffer from high blood pressure or migraines may need to consider alternative forms of contraception. A healthcare provider will help determine if the combined pill is a safe and effective option based on your medical history and lifestyle.
