Period pain: normal or not?
Did you grow up thinking that period pain is just part of life? Some discomfort, yes, happens. Pain that stops you in your tracks, no. Here’s how to tell the difference, and what you can do.
Written by Paul, a nurse, founder of EndoQueen. This guide informs; it doesn’t replace an appointment with a health professional.
Painful periods: what’s common, what isn’t
The medical word for painful periods is dysmenorrhoea. It’s common. But common doesn’t mean normal.
Fairly common: cramps in your lower belly, sometimes in your back, on the first day or two, that ease with a simple painkiller, a hot water bottle or rest.
Not to be brushed aside: pain that keeps you in bed, makes you miss school or work, makes you vomit or faint, or doesn’t ease with your usual painkillers. This kind of pain deserves a medical appointment.
Primary or secondary: two different situations
Primary dysmenorrhoea
It starts with your first periods or soon after. It’s usually not serious. Substances made at the time of your period, prostaglandins, make the womb contract, and these contractions hurt.
Secondary dysmenorrhoea
It starts later, or changes (stronger, longer, with other signs). The doctor then looks for a cause, such as endometriosis, adenomyosis or fibroids.
The line isn’t always clear: endometriosis can also cause painful periods from the teenage years.
Signs that mean it’s time to see a doctor
- The pain stops you going to school or work, or doing what you’d planned.
- Your usual painkillers don’t help enough, or you need to take a lot of them.
- The pain gets worse from one cycle to the next, or lasts beyond your period.
- You also have pain during sex, when you open your bowels or when you urinate, especially during your period.
- Your periods are very heavy, or you bleed between periods.
- You feel very tired, or dizzy.
- You’re having difficulty getting pregnant.
These signs only say: it’s time to talk about it. Your doctor decides which tests to do.
Emergency: call your local emergency number if the pain is sudden and unusual, if you have a fever with belly pain, if you feel faint or pass out, if the bleeding is very heavy, or if you could be pregnant and have severe pain on one side.
If you are having dark thoughts or feel in distress, contact a crisis line in your country or your local emergency number. You don’t have to cope alone.
And if you’re a teenager?
Painful periods are a major cause of missed school. If that’s you, you’re not exaggerating.
- Talk to a parent, the school nurse, your doctor or a midwife.
- You can see a doctor even if you’ve never had sex. A gynaecological examination isn’t always needed at a first appointment, and you can always say no or ask to wait.
- Note your cycles and your pain for two or three months: it helps the doctor enormously.
The European ESHRE guideline (2022) has a section on teenagers. It invites doctors to think of endometriosis in a young person with very painful periods, even if she’s young.
What you can do about period pain
To ease the pain
- Heat: a hot water bottle, a heat patch, a warm bath.
- A suitable painkiller, following the leaflet and the doses. Ask your pharmacist or doctor for advice, especially if you take other medicines or have a health condition.
- Moving gently if it helps (walking, stretching), or resting if that’s what you need.
Your doctor may also suggest other treatments, including hormonal ones. That’s a conversation to have with them, depending on your situation and what you want.
To be heard
Note each day you’re in pain: how strong it is out of 10, where it is, what you took, what it stopped you doing. After a few cycles, your doctor sees the pattern straight away. Our guide to preparing your appointment tells you what to bring and which questions to ask.
Frequently asked questions
Is it normal to have period pain?
Mild cramps that ease with a simple painkiller are common. Pain that makes you miss school or work, or that doesn’t go away, is a reason to see a doctor.
From what age can you see a doctor about painful periods?
As soon as the pain gets in the way of your life, whatever your age.
Do painful periods always mean endometriosis?
No. But severe pain that lasts or gets worse deserves to be looked into. Your doctor decides.
