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 diseases and conditions are examples of situations that can cause pain or cramps when not on your period.
Sometimes women in the very early stages of pregnancy experience 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.
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)
PID refers to an inflammation of the internal sex organs that usually results from 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.
Interstitial cystitis or painful bladder syndrome
Inflammatory bowel disease (IBD)
Irritable bowel syndrome (IBS)
