Key message: Some cramping around a period is common, but pain that disrupts school, work, sleep, sex or daily life deserves assessment. Worsening or later-onset pain can signal endometriosis, adenomyosis, fibroids, infection or another condition.
Get urgent help: Seek urgent care for sudden severe pelvic pain, fainting, fever or vomiting; a positive pregnancy test with pain or bleeding; heavy bleeding with weakness; a rigid or swollen abdomen; or pain after a procedure with worsening illness.
What is primary period pain?
Primary dysmenorrhoea is cramping without another identified pelvic disease. It often begins in the teenage years, starts just before or with bleeding and improves over one to three days.
Nausea, loose stools, headache or back pain can accompany the cramps.
Which features suggest another cause?
- Pain beginning after years of previously comfortable periods.
- Progressively worsening pain or pain throughout the cycle.
- Deep pain during or after sex.
- Pain with bowel movements or urination, especially around periods.
- Heavy, irregular or intermenstrual bleeding.
- Difficulty conceiving.
- Pelvic pain, fever or discharge outside the period.
What conditions may cause secondary pain?
- Endometriosis.
- Adenomyosis.
- Fibroids or an endometrial polyp.
- Pelvic inflammatory disease.
- An ovarian cyst or another pelvic mass.
- A copper IUD, particularly in the first months.
- Pregnancy-related or non-gynaecological causes when the pattern is atypical.
What can help at home?
- Heat applied safely to the lower abdomen or back.
- Gentle movement or exercise as tolerated.
- Regular sleep and meals.
- A cycle and symptom diary.
- Starting prescribed pain relief early, before pain becomes severe.
Which pain medicines are used?
Non-steroidal anti-inflammatory medicines are often most effective when started just before or at the beginning of pain, but they are unsuitable with some stomach, kidney, asthma, anticoagulant or pregnancy situations.
Paracetamol may be used when appropriate. Do not combine medicines or exceed doses without advice.
How can hormonal treatment help?
- Combined hormonal contraception can reduce ovulation and bleeding when medically suitable.
- Progestogen-only pills, implant, injection or hormonal IUS may reduce or stop periods.
- Treatment choice depends on contraception needs, migraine, clot risk, blood pressure, smoking and other conditions.
- Hormonal improvement does not prove a specific diagnosis; persistent symptoms still need review.
Which tests may be offered?
A normal ultrasound does not exclude endometriosis.
- Pregnancy test when relevant.
- Examination and infection testing when symptoms suggest it.
- Pelvic or transvaginal ultrasound.
- Blood tests for anaemia or another suspected cause.
- Specialist ultrasound, MRI or laparoscopy when endometriosis or another condition remains likely.
When should referral be considered?
Referral is appropriate when pain affects daily life, initial treatment is ineffective or not tolerated, fertility is affected or symptoms suggest deep endometriosis, adenomyosis, infection or another structural condition.
Repeated short prescriptions without reviewing the diagnosis can delay effective care.
Frequently asked questions
Is severe period pain normal because periods are supposed to hurt?
No. Mild cramps are common, but disabling pain deserves assessment.
Can a normal scan rule out endometriosis?
No. Superficial endometriosis may not be visible.
Should I take pain relief before bleeding starts?
For predictable pain, an NSAID may work best when started just before or at onset, if medically suitable.
Will hormonal contraception cure the cause?
It can control symptoms, but symptoms may return after stopping and some conditions need additional care.
Can period pain affect fertility?
The pain itself does not, but underlying conditions such as endometriosis or PID can.
Your next step
Bring a cycle and pain diary and previous treatment or scan results. Seek assessment when pain limits normal life, is worsening or occurs with heavy bleeding, sex, bowel or fertility symptoms.
