You still need contraception, your cycles have become unpredictable, and the method that suited you at 30 may not suit you at 47 — while the right choice can also treat the heavy bleeding and the hot flashes at the same time. Here is how the options compare in this specific decade, and when you can finally stop.
Where we stand: Menova is an independent publication. We sell no contraception and prescribe nothing, we are not your doctor, and this is general education, not medical or contraceptive advice.
Yes, you still need it
Fertility declines but does not vanish when cycles become irregular. Ovulation still happens, unpredictably, and pregnancy in the late forties carries higher risks for both mother and baby — which is why this is worth planning rather than assuming.
The standard guidance:
- Under 50: continue contraception for two years after your last natural period
- Over 50: continue for one year after your last natural period
- By 55, natural conception is regarded as exceptionally unlikely, and contraception is generally stopped
HRT is not contraception. This catches out a lot of women. Standard menopausal hormone therapy does not reliably prevent pregnancy, so if you are on HRT and still potentially fertile, you need a method alongside it.
The one that does three jobs
The hormonal IUD (levonorgestrel intrauterine system) is, for many women in this decade, the most efficient single choice — because it does three things at once:
- Highly effective contraception for several years
- Substantially reduces heavy bleeding, which is the dominant complaint of late perimenopause; see heavy periods in perimenopause
- Provides the progestogen component of HRT, so you can add estrogen for symptoms without a separate tablet — see progesterone in menopause
That combination is why it is so often recommended here. It is also useful in adenomyosis and fibroid-related bleeding; see fibroids in perimenopause.
Trade-offs: irregular spotting is common in the first three to six months, insertion is uncomfortable for some women (ask about pain relief options — this is a reasonable thing to request), and it does not treat hot flashes.
The combined pill, patch, or ring
Contains estrogen, so it can treat hot flashes and bleeding as well as prevent pregnancy — genuinely useful for some women in early perimenopause.
But eligibility narrows with age. Combined hormonal contraception is generally not recommended if you:
- Are over 35 and smoke
- Have migraine with aura, at any age — an important and frequently missed contraindication; see menopause and migraines
- Have a history of blood clots, or certain clotting disorders
- Have uncontrolled high blood pressure, or cardiovascular disease
- Have significant risk factors in combination
Guidance also generally suggests reviewing use as you approach 50. And a practical complication: the withdrawal bleed continues regardless of what your ovaries are doing, so it masks the transition entirely — see perimenopause while on birth control.
Progestogen-only options
Progestogen-only pill — suitable for most women including smokers over 35 and many with clot risk. Bleeding patterns vary from none to irregular spotting.
Implant — highly effective for three years, no daily routine, with unpredictable bleeding as the main drawback.
Injection — effective, but worth knowing that it is associated with reduced bone density with long-term use, which matters more as you approach the years when bone loss accelerates; see bone health in menopause. Usually reviewed carefully in this age group.
Non-hormonal options
Copper IUD — highly effective, hormone-free, lasts years, and can be left in place until contraception is no longer needed. The drawback is that it often makes periods heavier and more painful, which is the opposite of what most women want in perimenopause.
Condoms — no hormonal considerations, and the only method that also protects against sexually transmitted infections. Worth saying: STI rates in older adults have risen, and new partners in midlife are common. Condom use is not just a contraceptive decision.
Sterilisation — permanent, for either partner. Vasectomy is a simpler procedure with a lower complication rate than female sterilisation, and it is often not discussed.
Fertility awareness methods — considerably less reliable when cycles are irregular, which is precisely the situation in perimenopause.
Choosing by what bothers you most
A practical way to narrow it:
- Heavy bleeding is the main problem → hormonal IUD
- Hot flashes plus contraception, and you are eligible → combined pill, patch or ring in early perimenopause
- You cannot take estrogen → hormonal IUD, progestogen-only pill, or implant
- You want no hormones at all → copper IUD or condoms
- You are certain you are finished → sterilisation, or a long-acting method until you can stop
- You want HRT and contraception together → hormonal IUD plus estrogen
How do I know when to stop, if I have no periods?
The awkward case: if your method has removed your bleeding altogether, you cannot count twelve months.
Options your clinician may use:
- Continue until 55, which is the simplest approach and what many women do
- Measure FSH twice, several weeks apart, in women over 50 on progestogen-only methods — sometimes used as supporting evidence. This does not work reliably on combined hormonal contraception, which suppresses FSH
- Switch to a non-hormonal method for a period to observe your own pattern — a real option, but one with contraceptive consequences to plan rather than improvise
This is a specific conversation to have rather than something to work out alone.
What to ask
- Given my age, my migraine history, and my blood pressure, which methods are still appropriate for me?
- Would a hormonal IUD cover my bleeding, my contraception, and the progestogen part of HRT?
- When can I stop, and how will we know?
- If I want to treat hot flashes too, what fits alongside this method?
Bring your blood pressure reading and your migraine history — including whether you get aura — because both change the answer immediately. The free printable visit prep sheet has space for exactly that, and the free 30-day symptom tracker gives you the bleeding record that makes the conversation concrete.
The free 2-minute Menova self-check organizes your wider symptom picture — no account, not a diagnosis, and your answers never leave your device.
If you already have a hormonal IUD, the question of when it expires and how you know where you are — given that it may have stopped your periods — is covered in when does my coil come out. See also am I pregnant, or is this perimenopause and was that my last period.
Whatever else is going on, unexpected bleeding needs assessing rather than explaining away. Any bleeding after twelve months without periods, bleeding that is new or persistent on hormone therapy, or bleeding after sex should be assessed in person — see bleeding after menopause and bleeding on HRT.
