Several conditions can cause cramps but no period.

Pelvic pain similar to a menstrual period can happen at times when no period is due or can occur because of conditions other than the monthly cycle. Sometimes it is hard to tell the exact reason for cramps that feel like a menstrual period.

The following 12 diseases and conditions are examples of situations that can cause pain or cramps when not on your period.


In the middle of the menstrual cycle, or about 10-14 days before your period, ovulation occurs. This is the release of an egg from a follicle within the ovary.

  • Symptoms can include
    • mild cramping that may be sharp or dull,
    • lasting a few minutes to hours. It typically occurs on one side of the abdomen only.

Ovarian cyst

A cyst is an enclosed tissue sac filled with fluid. The ovary is a common location for cyst development.

  • A small ovarian cyst typically does not cause symptoms, but if the cyst ruptures, it can cause sudden, sharp pains or cramps on one side of the lower abdomen.
  • An enlarging cyst may cause dull pain or a feeling of fullness or heaviness in the lower abdomen or back.

Ovarian cancer

This is a rare cause of pain or pressure within the abdomen or pelvis.

  • Ovarian cancer may not cause any symptoms, but if the cancer is large, it can cause
    • pain or pressure in the abdomen or back,
    • a feeling of heaviness or fullness,
    • swelling of the abdomen, and
    • feeling an urgent need to urinate.

  • Hot flashes
  • Breast tenderness
  • Nausea
  • Night sweats
  • Weight gain
  • Decreased fertility
  • Loss of bone density
  • Mood changes
  • Altered blood cholesterol levels

Pregnancy, ectopic pregnancy and endometriosis

Sometimes women in the very early stages of pregnancy experienced slight cramping, similar to mild menstrual cramps, right around the time that the fertilized egg implants in the uterus. This is termed “implantation pain” and happens right around the time of the expected period.

  • Usually, there are no other symptoms at this time other than the absence of a period. Sometimes there is light spotting at the time of implantation.

Ectopic pregnancy

An ectopic pregnancy refers to a fertilized egg attaching in an abnormal location outside of the uterus (womb), typically in the fallopian tubes.

  • A ruptured ectopic pregnancy can lead to sudden, severe sharp pains in the lower abdomen that can spread to the back.
  • Before this happens, there may be the typical symptoms of early pregnancy like


This is a condition in which tissue, similar to that found inside the uterus, grows in other locations outside of the uterus. It is a very common condition.

    • infertility,
    • painful bowel movements, or
    • pain during sex in some women.
