Cramps you never used to get, or cramps you had at twenty that came back harder. It is a common and under-discussed part of the transition, it is frequently met with "that's just your age", and there are specific things that work — including one that most women are using at the wrong time.

Where we stand: Menova is an independent publication. We sell no medication and no supplements, we are not your doctor, and this is general education, not a diagnosis.

Why it changes now

Two things, and they usually travel together.

The bleeding gets heavier. Cycles increasingly happen without ovulation, which means little or no progesterone in the second half and a lining that builds more than it used to. More lining means more to shed, more clots, and stronger contractions to shift it — see heavy periods in perimenopause.

Conditions that cause pain become more common or more established in this decade. That is the part worth taking seriously rather than absorbing.

The four worth naming

Adenomyosis — where lining tissue grows into the muscular wall of the uterus. Classically a heavy, painful period with a dragging, bruised quality and a uterus that feels bulky. It is common, it peaks in the forties, and it is under-diagnosed because the symptoms get filed as "bad periods". See endometriosis and adenomyosis in perimenopause.

Fibroids, which can cause pain, pressure, and heavy bleeding, and which are very common by this age — see fibroids in perimenopause.

Endometriosis, usually longstanding rather than new, and often diagnosed late after years of being told the pain was normal.

Clots and volume. Passing large clots produces cramping that is mechanical rather than pathological — but the volume causing it is itself treatable.

A distinction worth holding: pain you have had since your teens that is now worse behaves differently from pain that is genuinely new in your forties. New warrants more attention, not less.

The thing most women get wrong about painkillers

Anti-inflammatories work better taken to a schedule than taken when the pain arrives.

They work by blocking the prostaglandins that drive uterine contractions. Once those are already produced, you are trying to catch up. Starting at the first sign — or the day before, if your cycle is predictable enough — and continuing at regular intervals for the first day or two is meaningfully more effective than waiting until it hurts and then hoping.

They also reduce blood loss, which is a genuine dual benefit most people do not know about, and one reason they are a first-line option for heavy periods rather than just a comfort measure.

Who should check first: anyone with stomach ulcers or reflux, kidney problems, asthma made worse by these drugs, or who takes anticoagulants — see anticoagulants and heavy bleeding and HRT and everything else you take.

Ask a pharmacist which is appropriate for you and at what dose. This is exactly the kind of question they are there for and it takes two minutes.

The other options, briefly

Because "take some ibuprofen and get on with it" is not the whole menu.

Tranexamic acid reduces bleeding substantially and is taken only on heavy days. It does not treat pain directly, but less volume usually means less cramping — see comparing the treatment options.

A hormonal IUD thins the lining, and for many women periods become much lighter or stop. It also handles contraception and can serve as the progestogen part of hormone therapy — see when does my coil come out.

Combined hormonal contraception, where suitable, which can regulate and lighten periods — see perimenopause on birth control and contraception in perimenopause.

Procedures, if bleeding and pain are severe and medication has not worked — see the treatment options and hysterectomy and menopause.

Heat genuinely helps and has reasonable evidence behind it, which is unusual for something free.

Exercise and TENS help some people. Neither is a substitute for treating heavy bleeding.

What does not earn its place

Supplements marketed for period pain. Evidence is weak across the category — see what the supplement research says.

Waiting it out until menopause. Adenomyosis and fibroids do usually improve after periods stop, and that may be years away. Untreated heavy bleeding in the meantime drains iron — see low ferritin in perimenopause.

Get it looked at rather than managed

  • Pain that is new in your forties without a history of painful periods
  • Pain that is not cyclical — constant, or unrelated to your period
  • Pain during sex, which is a different question — see when sex hurts
  • Pain with fever or unusual discharge, which suggests infection
  • Pain with bleeding after twelve months without periods — see bleeding after menopause
  • Persistent bloating, feeling full quickly, or urinary urgency alongside the pain — see the symptoms worth checking anyway
  • Sudden severe pelvic pain, which needs urgent assessment
  • Bleeding heavy enough to plan your life around, which is treatable rather than something to accept

What to say

"My periods have become much more painful over the last two years and heavier with it — I'm using four times the protection I used to. Ibuprofen barely touches it. Could we look at whether this is adenomyosis or fibroids, and talk about tranexamic acid or a hormonal coil?"

That gives a timeline, quantifies the bleeding, reports that first-line treatment has failed, and names the options — which moves the conversation past "period pain is normal".

Our free 30-day symptom tracker records the dates, heaviness and pain together, which is what makes the pattern visible. The free printable visit prep sheet keeps it to one page, and if you are being drained by the bleeding, the free blood test sheet covers the ferritin question.

The line worth holding

Periods becoming more painful is common. Common is not the same as untreatable, and "it will settle when you get to menopause" is a description of the timeline, not a plan for the years in between.

This article is general education, not medical advice or a diagnosis. Do not start regular anti-inflammatory use without checking it is appropriate for you. Sudden severe pelvic pain, pain with fever, or bleeding after twelve months without periods requires prompt assessment by a licensed clinician.
