Some period pain is normal. Cramping that's manageable with paracetamol or ibuprofen, lasts a day or two, and doesn't stop you living your life is common and expected. Period pain that stops you working, studying, or leaving the house, or that keeps getting worse month after month, isn't something you're supposed to just push through, and it's worth taking seriously.
👉 "Just part of being a woman" is not a diagnosis. It's often exactly the phrase that delays one.
I'll be honest about why I ended up going deep on this one. So many women in the Maia community have mentioned, almost in passing, that their periods have always been "bad," as if that were just a fact about their bodies rather than a symptom worth investigating. Some of them were trying to conceive for months before anyone connected the dots. This is me trying to lay out what I actually learned, properly sourced, not just repeating what gets said around it.
What Counts as Normal Period Pain?
Mild to moderate cramping in your lower abdomen, sometimes spreading to your lower back or thighs, in the day or two before or during your period, is genuinely common. This is called primary dysmenorrhoea, and it happens because your uterus contracts to shed its lining, triggered by hormone-like chemicals called prostaglandins.
The NHS describes typical period pain as something that usually responds to over-the-counter pain relief, a hot water bottle, and gentle movement, and that eases within a day or so of your period starting.
That's the baseline. It's not nothing, but it shouldn't be running your life.
When Is Period Pain Not Normal?
This is called secondary dysmenorrhoea when there's an underlying cause (the NHS's own endometriosis page is a good primary reference for this), and it's worth taking seriously if your period pain:
- Stops you doing normal things, like going to work, school, or exercising
- Gets worse over successive cycles, rather than staying roughly the same
- Lasts longer than your period itself, rather than easing within a day or two
- Doesn't respond to standard pain relief (paracetamol, ibuprofen) at normal doses
- Comes with heavy bleeding or large clots
- Happens alongside pain during sex
- Shows up as pelvic pain between periods, not just during them
If several of these sound familiar, it's a genuinely good reason to see a GP, not something to quietly manage around indefinitely.
What Actually Causes Severe Period Pain?
A few real, named conditions are behind most cases of period pain that goes beyond the ordinary:
- Endometriosis: tissue similar to the uterine lining grows outside the uterus (on the ovaries, fallopian tubes, bladder, bowel, or pelvic cavity), where it still responds to your hormonal cycle but has nowhere to go, causing inflammation, pain, and sometimes scar tissue.
- Adenomyosis: similar tissue grows into the muscular wall of the uterus itself, which can cause heavy, painful periods and an enlarged uterus.
- Fibroids: non-cancerous growths in or around the uterus, which can cause pain and heavy bleeding depending on size and position.
- Pelvic inflammatory disease (PID): infection of the reproductive organs, usually needing antibiotic treatment.
Sometimes intense cramping happens without any of these being present at all. Not every case of severe period pain has an identifiable underlying condition, but it's still worth ruling one out.
Endometriosis Specifically: Why It Gets Missed So Often
Endometriosis deserves its own section because it's genuinely common (thought to affect around 1 in 10 women of reproductive age) and genuinely under-diagnosed.
Symptoms that go beyond a typical bad period include:
- Intense period pain that interferes with daily life
- Pain during sex
- Heavy or irregular periods
- Digestive symptoms around your period (bloating, constipation, nausea)
- Lower back pain
- Persistent fatigue
- Pain when peeing or passing stools, especially during your period
- Difficulty conceiving
None of these on their own confirm endometriosis. Together, especially if several show up consistently, they're a real reason to ask your GP directly about it, by name.
The Real Diagnosis Delay
I want to correct something I initially had wrong here too: a lot of content quotes "7 to 10 years" as the average UK diagnosis delay for endometriosis. That figure is out of date. Endometriosis UK's most recent report (2026) puts the real current average at 9 years and 4 months, up from 8 years in 2020, and it's even longer for ethnically diverse communities, at around 11 years. Around 1 in 4 people surveyed needed 10 or more GP visits before endometriosis was even suspected.
That's not a small gap. It's the difference between catching something early and living with it, unexplained, for the better part of a decade.
It wasn't about not speaking up, it was about not being believed the first several times.
The only way to definitively confirm endometriosis is currently a laparoscopy, a small surgical procedure. A GP can start that process, and can also request pelvic ultrasounds or an MRI as an earlier step, even though these can't rule endometriosis out on their own.
How Period Pain and Endometriosis Can Affect Fertility
Not everyone with endometriosis struggles to conceive, but a meaningful number do, for a few real, mechanical reasons:
- Scar tissue from endometriosis can physically block the fallopian tubes
- Inflammation can interfere with ovulation or with an embryo implanting successfully
- Hormonal disruption can make cycles less predictable, which makes tracking ovulation and timing genuinely harder
Pregnancy is still very much possible with endometriosis, whether naturally or with support like IUI, IVF, or laparoscopic surgery to remove lesions. If you're TTC with a period pain condition, tracking ovulation carefully (LH strips, basal body temperature, or cervical mucus monitoring) tends to matter even more than usual, since cycles can be less predictable to begin with -- a tracking kit that covers LH and BBT in one place can make this genuinely easier to stay on top of. Our guide on coping with TTC stress is also worth reading if trying to conceive alongside painful periods is weighing on you.
When to See a Doctor, and When It's Urgent
See a GP if:
- Pain regularly stops you doing normal daily activities
- Pain has been getting worse over several cycles
- Standard pain relief isn't touching it
- You have pain during sex
- You're struggling to conceive alongside painful, heavy, or irregular periods
Get urgent medical advice (NHS 111, an urgent GP appointment, or A&E) if you have sudden, severe pelvic pain, particularly if it comes with fever, vomiting, or you feel faint, since this occasionally signals something needing immediate attention (like an ovarian cyst rupture or torsion) rather than period pain itself. The NHS's own urgent-advice guidance is worth reading directly if you're ever unsure in the moment.
What Actually Helps With Period Pain
While you're figuring out whether there's an underlying cause, or managing alongside one, a few things genuinely help most people:
- Heat. A hot water bottle against your lower abdomen or back is one of the simplest, best-evidenced ways to ease cramping.
- Gentle movement. Walking or gentle yoga can help, even when it's the last thing you feel like doing.
- Anti-inflammatory eating patterns. Diets higher in omega-3s and leafy greens, lower in processed sugar and dairy, are commonly discussed for period pain, though the evidence here is more mixed than for heat or movement, so treat it as worth trying rather than guaranteed.
- Standard pain relief, used properly. Ibuprofen works partly by reducing the prostaglandins that cause cramping in the first place, so taking it at the first sign of pain (rather than waiting until it's severe) tends to work better.
- Pelvic physiotherapy or acupuncture. Both are worth exploring if pain is a recurring issue, particularly alongside a suspected condition like endometriosis.

Medical Options Worth Knowing About
If lifestyle measures aren't enough on their own, there are real medical options a GP can discuss with you, though it's worth being upfront that some of these (particularly hormonal ones) aren't compatible with actively trying to conceive, so which ones make sense depends a lot on where you are in your TTC journey.
Stronger prescription pain relief. If over-the-counter ibuprofen or paracetamol genuinely isn't touching the pain, a GP can prescribe something stronger, or a combination that works better for you specifically.
Hormonal treatments (the combined pill, the progestogen-only pill, or a hormonal coil) can reduce period pain significantly for many people by thinning the uterine lining or suppressing ovulation. These genuinely help a lot of people with painful periods, endometriosis included, but they're contraceptive, so they're not the right conversation to have while actively trying to conceive. Worth knowing about for before or after a TTC window, not necessarily during it.
Tranexamic acid can be prescribed specifically for heavy bleeding alongside pain, without affecting hormones or fertility, which makes it a genuinely useful option to ask about if heavy flow is a big part of what's making your periods difficult.
Laparoscopic surgery to remove endometriosis lesions is an option for confirmed endometriosis causing significant pain or fertility difficulty, and can improve both symptoms and conception chances for some people, though it's a bigger step usually reserved for when other approaches haven't worked.
None of these are a first step. They're worth knowing exist so a GP conversation feels like a genuine discussion of options rather than you walking in blind.
FAQ: Period Pain
How much period pain is normal?
Mild to moderate cramping that responds to over-the-counter pain relief and eases within a day or two of your period starting is common. Pain that stops your normal activities or keeps getting worse isn't something to just accept as normal.
What causes severe period pain?
Endometriosis, adenomyosis, fibroids, and pelvic inflammatory disease are the most common underlying causes. Sometimes intense cramping happens without an identifiable cause at all.
How do I know if my period pain is too severe?
If it consistently stops you working, studying, exercising, or doing normal daily activities, or if standard pain relief doesn't help, it's a good reason to see a GP.
Can endometriosis cause fertility problems?
It can, through scar tissue, inflammation, or hormonal disruption, but many people with endometriosis still conceive naturally or with medical support.
When should I go to A&E for period pain?
Sudden, severe pelvic pain, especially with fever, vomiting, or feeling faint, needs urgent medical attention rather than home management, since it can occasionally signal something like an ovarian cyst rupture.
How long does it take to get diagnosed with endometriosis in the UK?
The current average is 9 years and 4 months, according to Endometriosis UK's most recent (2026) report, longer than the "7 to 10 years" figure that's often quoted, and even longer for ethnically diverse communities.
Why are periods so painful for some people and not others?
Individual prostaglandin levels, pain sensitivity, and whether an underlying condition like endometriosis or adenomyosis is present all play a role. It's rarely just one factor.
If nothing else, this is worth saying plainly: you don't need a diagnosis to be allowed to say your period pain isn't normal, and you don't need to wait nine years to be taken seriously. Trust what your body is telling you, write it down, and keep asking, even if the first answer you get is "that's just periods." Sometimes it is. Sometimes it very much isn't, and you're the only one who can keep pushing to find out which.
