Mid-Cycle Pain (Mittelschmerz)
You have pain during the middle of your menstrual cycle. This is called mid-cycle pain (mittelschmerz). It's caused by ovulation. Ovulation happens around the middle of the menstrual cycle when an egg is released from one of the ovaries. In some people, this causes sharp, cramping pain in one side of the lower belly (abdomen). It can last from a few minutes to a day or so. You may feel the pain every month or only once in a while. The pain may also switch sides from month to month.
In most cases, mid-cycle pain is not a serious problem. Treatment is focused on symptom relief. If needed, medicine may be prescribed.
