Why do I have 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.
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.
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.
- 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.
Pelvic inflammatory disease (PID), interstitial cystitis or painful bladder syndrome and appendicitis
PID refers to an inflammation of the internal sex organs that usually results from the spread of a sexually transmitted disease. It is usually caused by bacteria that spread from the vagina and cervix upward into the uterus, tubes, and ovaries.
- PID causes lower abdominal pain on both sides of the body, often accompanied by
Interstitial cystitis or painful bladder syndrome
This is a condition that results from chronic inflammation of the bladder. It can cause pain at any time of the month.
- Symptoms typically get worse when the bladder is full (when you have to urinate). It can cause pain and tenderness in the low abdomen or pelvic area. Other possible symptoms are
- painful urination and
- feeling an urgent need to urinate.
Inflammatory bowel disease (IBD), irritable bowel syndrome (IBS) and indigestion
- Symptoms depend on the severity and exact type of IBD but usually include some type of abdominal pain.
- Other symptoms can include
Irritable bowel syndrome (IBS)
- Symptoms of IBS can vary from mild to severe. Typical symptoms include
