Contraception in perimenopause

A long gap between periods doesn’t mean you can’t get pregnant. During perimenopause, you may still release an egg in some months, even after missing periods. If you want to avoid pregnancy, ask about contraception at your menopause appointment too.

When contraception can end depends on where you get care

Advice differs between countries. In the UK, how long to wait depends on your age when your natural periods stop. US public information says menopause comes after 12 months without bleeding. It advises using contraception until one full year after your last period. If medicines are changing your bleeding, ask how this advice applies to you.

Guidance	What it says
UK: NHS	Use contraception for 2 years after your last period if you are 40 to 49. Use it for 1 year if you are 50 or over.
US: Office on Women’s Health	Carry on until one full year after your last period, with advice about your contraception needs.
US: CDC	Points to expert advice to carry on until menopause or age 50–55 years, taking health risks into account.

UK guidance from Women’s Health Concern says you can usually stop contraception at age 55. Ask your clinician to confirm the plan for your method. Don’t stop a prescribed contraceptive without talking to your doctor. And don’t have a device removed just because an app shows a gap in your periods.

How contraception affects bleeding

The combined pill can cause a bleed in the break between packs (a withdrawal bleed), even when your natural periods would have stopped. Progestogen-only methods can make bleeding irregular or stop it. Neither pattern on its own tells you whether you’ve reached menopause. A clinician needs to take your method into account.

CDC says no reliable lab test can confirm that fertility has ended for good. A blood test alone can’t tell everyone when to stop contraception. UK guidance allows testing in some people using progestogen-only methods. It says blood tests aren’t reliable if you use combined hormonal contraception.

Choosing a method as your needs change

UK guidance says the combined pill, patch and ring can be used up to age 50 by people without health risks that rule them out. Smoking, high blood pressure and migraine with aura (warning signs such as flashing lights before a migraine) are among the things a clinician checks. Plan a review around this age rather than changing your prescription yourself.

UK guidance says the progestogen-only pill and the implant can be used until age 55. The injection needs a separate talk about bone health and other options around age 50. US CDC guidance doesn’t rule out hormonal methods or IUDs because of age alone. Other health conditions can affect whether a method suits you.

A hormonal coil can ease period pain and bleeding. A copper coil has no hormones but can make periods heavier or more painful. Condoms also help protect against sexually transmitted infections. Ask how these differences fit with what you want, and how comfortable and easy each method would be.

Fit HRT and contraception into the same plan

HRT doesn’t prevent pregnancy. Some hormonal coils can give you the progestogen part of HRT as well as contraception. But the time to replace them can differ depending on what they’re used for. Ask your prescriber to note what your device is being used for and when it needs checking.

As your cycles and ovulation become harder to predict, period timing becomes less reliable for fertility awareness methods. Ruva’s estimates are never contraception.

When to ask for help

If you want to avoid pregnancy, get help today after unprotected sex or if your contraception failed. In the UK, contact a pharmacist, GP or sexual health clinic. In the US or elsewhere, contact a pharmacist, doctor or sexual health service. Emergency contraception works better the sooner you use it. Having menopause symptoms doesn’t mean you don’t need to ask.

Book a routine contraception review before changing methods. Get a medical check for new bleeding after a long time without any, including if you use a hormonal method. Bring the name of your method and any HRT details so the clinician can look at them together.
