Mittelschmerz is one-sided, lower abdominal pain associated with ovulation. German for "middle pain," mittelschmerz occurs midway through a menstrual cycle — about 14 days before your next menstrual period.

In most cases, mittelschmerz doesn't require medical attention. For minor mittelschmerz discomfort, over-the-counter pain relievers and home remedies are often effective. If your mittelschmerz pain is troublesome, your doctor may prescribe an oral contraceptive to stop ovulation and prevent midcycle pain.

Female reproductive system

The ovaries, fallopian tubes, uterus, cervix and vagina (vaginal canal) make up the female reproductive system.


Mittelschmerz pain usually lasts a few minutes to a few hours, but it may continue for as long as a day or two. Pain from mittelschmerz may be:

Mittelschmerz pain occurs on the side of the ovary that's releasing an egg (ovulating). The pain may switch sides every other month, or you may feel pain on the same side for several months.

Keep track of your menstrual cycle for several months and note when you feel lower abdominal pain. If it occurs midcycle and goes away without treatment, it's most likely mittelschmerz.

When to see a doctor

Mittelschmerz rarely requires medical intervention. However, contact your doctor if a new pelvic pain becomes severe, if it's accompanied by nausea or fever, or if it persists — any of which could indicate you have a condition more serious than mittelschmerz, such as appendicitis, pelvic inflammatory disease or even an ectopic pregnancy.


Mittelschmerz occurs during ovulation, when the follicle ruptures and releases its egg. Some women have mittelschmerz every month; others have it only occasionally.

The exact cause of mittelschmerz is unknown, but possible reasons for the pain include these:

Pain at any other point in your menstrual cycle isn't mittelschmerz. It may be normal menstrual cramping (dysmenorrhea) if it occurs during your period, or it may be from other abdominal or pelvic problems. If you have severe pain, see your doctor.

Risk factors

Mittelschmerz has no clear risk factors. But it may be more likely to happen between the ages of 15 and 25.


Mittelschmerz doesn't lead to other health conditions, also called complications. The pain goes away on its own, or with medicine or home remedies.


Mittelschmerz can't be prevented. It's linked with natural changes in the body that happen during the menstrual cycle.


To diagnose mittelschmerz, your doctor will start by asking you questions to get a clear idea of your medical history, especially regarding your menstrual periods. Your doctor may also perform a physical exam, including a pelvic exam, to check for signs of an underlying condition that could be contributing to the pain.

Pelvic exam

During a pelvic exam, a doctor inserts one or two gloved fingers inside the vagina. Pressing down on the abdomen at the same time, the doctor can check the uterus, ovaries and other organs.


Possible treatments for mittelschmerz include:
