Pill, Patch, Ring & Injection
The Pill (Oral Contraceptives)
The contraceptive pill is a widely used, hormone-based birth control method taken orally each day. There are two main types:
Combined Pill
Contains two hormones, oestrogen and progestogen, which work together to prevent ovulation (the release of an egg).
Progestogen-Only Pill (Mini Pill)
Contains only progestogen and primarily works by thickening cervical mucus, making it difficult for sperm to reach the egg. It may also thin the womb lining and, in some cases, suppress ovulation.
Frequency
The pill must be taken once daily, ideally at the same time every day.
Combined Pill
Typically taken for 21 days, followed by a 7-day break or with placebo pills during which a withdrawal bleed occurs.
Mini Pill
Taken continuously with no break between packs.
Typical Side Effects
While many people tolerate the pill well, some may experience side effects, especially in the first few months, including:
- Nausea or slight stomach upset
- Breast tenderness or swelling
- Mood changes, irritability, or low mood
- Breakthrough bleeding or spotting between periods
- Headaches or changes in libido
Most side effects subside after a few weeks, but if they persist or worsen, it may be worth discussing alternative pill types or methods with a healthcare provider.
Effectiveness
- Perfect use: over 99% effective (no missed pills).
- Typical use: around 91% effective — roughly 9 in 100 users may become pregnant each year.
Setting daily reminders or using pill tracking apps can help improve consistency.
Contraceptive Patch
The contraceptive patch is a small skin patch that releases oestrogen and progestogen into the bloodstream. These hormones prevent ovulation and thicken cervical mucus, making it harder for sperm to reach an egg.
Frequency: one patch per week for 3 weeks, then a 1-week break.
Typical Side Effects
Mild skin irritation at the application site is common, especially during the first few weeks. Other side effects may include headaches, breast tenderness, nausea, and, in some cases, changes in mood or spotting between periods.
Effectiveness
With typical use, the patch is around 91% effective (about 9 in 100 women may become pregnant each year). When used correctly and consistently, its effectiveness is over 99%.
Vaginal Ring (NuvaRing)
The vaginal ring is a small, flexible, plastic ring inserted into the vagina, where it steadily releases oestrogen and progestogen. These hormones prevent ovulation and thicken cervical mucus. Because the hormones are delivered locally, lower doses are required compared to some other hormonal contraceptives.
Frequency: left in place for 3 weeks, removed for 1 week.
Benefits
- Only needs replacing once a month, reducing the need for daily attention like the pill.
- Provides steady hormone release, which can result in lighter, more regular periods.
- Can be removed for up to three hours during sex if desired, without reducing effectiveness.
Typical Side Effects
- Mild vaginal irritation or discomfort
- Increased vaginal discharge
- Headaches or migraines
- Breast tenderness
- Mood changes or changes in libido
- Spotting or irregular bleeding in the first few months
Effectiveness
With typical use, the vaginal ring is around 91% effective (9 in 100 women may become pregnant each year). When used perfectly, effectiveness increases to over 99%.
Contraception Injection
The contraceptive injection (e.g. Depo-Provera) delivers progestogen into a muscle or under the skin. It prevents ovulation, thickens cervical mucus to block sperm, and thins the womb lining to reduce implantation chances.
Frequency: every 8–13 weeks depending on the formulation.
Typical Side Effects
- Irregular or unpredictable bleeding patterns, especially in the first months
- Possible weight gain or increased appetite
- Headaches or mood changes
- Potential for bone mineral density loss with long-term use (usually reversible)
- Delayed return to fertility, which can take up to a year after stopping
Effectiveness
With typical use, the injection is about 94% effective (6 in 100 women may become pregnant each year). With perfect use (timely injections), effectiveness rises to over 99%.
Long-Acting Reversible Methods (LARC)
Intrauterine Device (IUD)
The IUD is a small, T-shaped device inserted into the womb by a trained healthcare professional. There are two main types:
Copper IUD
Uses copper to create an environment toxic to sperm and eggs, preventing fertilisation.
Hormonal IUD (e.g. Mirena, Kyleena)
Releases progestogen, which thickens cervical mucus, thins the womb lining, and may suppress ovulation in some women.
Frequency
Copper IUD
Provides protection for 5–10 years depending on the type.
Hormonal IUD
Provides protection for 3–5 years depending on the brand. Once inserted, no daily or weekly maintenance is needed, making it a “fit and forget” option.
Benefits
- Long-term contraception without user error.
- Highly effective and reversible upon removal.
- Copper IUD is hormone-free, ideal for those who cannot use hormonal contraception.
- Hormonal IUD often reduces menstrual pain and bleeding, and may even stop periods altogether over time.
Typical Side Effects
- Irregular spotting or bleeding in the first 3–6 months.
- Hormonal IUD: possible headaches, breast tenderness, or mood changes.
- Copper IUD: may cause heavier or more painful periods, particularly in the first few months.
- Mild discomfort or cramping during insertion (usually short-lived).
Effectiveness
- Over 99% effective at preventing pregnancy.
- Fertility returns quickly after removal, making it a flexible option for long-term but reversible contraception.
Contraceptive Implant (e.g. Nexplanon)
The contraceptive implant is a small, flexible plastic rod inserted under the skin of the upper arm by a trained healthcare professional. It steadily releases progestogen, which prevents ovulation, thickens cervical mucus, and thins the womb lining to prevent implantation.
Duration
- Provides continuous protection for up to 3 years.
- Once inserted, there is no need for daily, weekly, or monthly action, making it a “fit and forget” method.
Benefits
- Highly effective long-term contraception with no user error.
- Can be removed at any time, with fertility typically returning quickly.
- Suitable for women who cannot use oestrogen-containing methods.
- May reduce period pain and, in some cases, stop periods completely.
Typical Side Effects
- Irregular or unpredictable bleeding patterns (most common).
- Possible headaches or dizziness.
- Mood changes, including irritability or low mood.
- Acne or skin changes in some users.
- Minor bruising or tenderness at the insertion site (short-term).
Effectiveness
- Over 99% effective at preventing pregnancy.
- One of the most reliable contraceptive methods available, with no need to remember pills or patches.

FAQs
Where can I get contraception in the UK, and is it free?
Most types of contraception are free through the NHS. You can access them from your GP surgery, contraception and sexual health clinics (GUM clinics), some pharmacies that provide certain pills and emergency contraception, and trusted NHS-partnered online services that can prescribe and deliver contraception discreetly.
What types of contraception are available?
Options include short-acting methods such as the combined pill, mini pill, patch, and vaginal ring, as well as long-acting reversible contraception (LARC) like implants, hormonal coils (IUS), non-hormonal coils (IUD), and injections. Barrier methods include condoms, diaphragms, and caps, while permanent options include sterilisation and vasectomy.
How do I choose the right method?
The best method depends on your health, lifestyle, and personal preferences — effectiveness, any medical conditions, convenience (daily pills versus “fit and forget” methods), how each option affects your periods, and whether you are planning to have children soon. Your GP or nurse can help you choose.
What are LARCs and why are they recommended?
Long-acting reversible contraception (LARC), such as implants, coils, and injections, are highly recommended because they are over 99% effective and don’t require daily attention. Once fitted, they provide reliable protection for months or even years.
What if I make a mistake (e.g. miss a pill)?
Check the instructions in your patient information leaflet, as guidance varies by pill or device. You may need to use condoms for a short period or consider emergency contraception. If unsure, speak to a pharmacist, GP, or sexual health clinic as soon as possible.
Will contraception affect my periods or cause side effects?
Hormonal contraception can change your bleeding pattern, making periods lighter, more irregular, or stopping them altogether. Some people experience headaches, mood changes, nausea, or breast tenderness, which often improve after the first few months. The non-hormonal copper IUD may make periods heavier or more painful.
Does contraception protect against STIs?
Only condoms offer protection against sexually transmitted infections. Other methods like pills, coils, or implants prevent pregnancy but not STIs, so using condoms alongside another method (dual protection) is the best way to stay protected.
When and how can I get emergency contraception?
Emergency contraception can be used after unprotected sex or contraceptive failure. Emergency pills such as Levonelle (up to 3 days after) or ellaOne (up to 5 days) are options, and the copper IUD is the most effective, fitted up to 5 days after. It is available free from GPs and clinics, or to buy in most pharmacies.
How easy is it to switch or stop contraception?
Switching or stopping is straightforward and can be done at any time with the help of a GP or clinic. For most methods, fertility returns quickly. However, it may take up to a year for fertility to return to normal after using the contraceptive injection.
Are visits confidential, even if I’m under 16?
Yes, contraception services in the UK are confidential for all ages. If you are under 16, healthcare professionals will not inform your parents or carers as long as you understand the advice and decisions you are making, following the Fraser Guidelines.
