Period cramps but no period: common causes

Period-like cramps without a period are common. The most likely reasons are that your period is about to start, you are ovulating, or your gut is the source. Early pregnancy can cause mild cramps too. Severe or one-sided pain with a missed period needs urgent checking.

Why do I have cramps but no period?

• Your period is on its way: cramps often start a day or two before bleeding.
• Ovulation pain: a one-sided ache mid-cycle.
• Early pregnancy: mild cramps with a late period. A test can tell.
• Gut causes: constipation, wind and IBS can feel very like period pain.
• A late period: stress, illness, travel or weight change can delay ovulation, and the period with it.
• Conditions: endometriosis, adenomyosis and fibroids can cause pain outside periods.
• Infection: pelvic inflammatory disease or a UTI, often with other symptoms.

Cramps but no period and a negative test: what next?

If you tested before your period was due, the result may be too early: test again in a few days. If you have tested after a missed period and it is negative, stress, weight change, exercise, contraception and PCOS are common reasons for a late period. If you miss three periods in a row and are not pregnant, see a GP.

What helps the pain?

• Heat: a hot water bottle or warm bath.
• Ibuprofen or paracetamol, if they are suitable for you.
• Gentle movement such as walking or stretching.
