(HealthDay News) -- Ovarian cysts are small sacs of fluid or semi-solid material that form on a woman's ovary.

Most of the time they do not indicate disease, and they may go away without treatment within a few months. But the U.S. National Library of Medicine (NLM) says you should see your doctor if you have any symptoms to rule out a more serious condition.

Here is the NLM's list of the most common symptoms of ovarian cysts:

• Dull, persistent pain in the abdomen.
• Pain during menstruation, intercourse, bowel movements or movement of the pelvis.
• Unusual uterine bleeding or abnormal menstrual cycles
• Missing a period.
• Bloated or swollen abdomen.
