Cramping during mid-cycle is a quite common condition for women of childbearing age.

Ovulation happens on day 14 (if your menstrual cycle lasts 28 days), when your ovary produces an egg so it can be fertilized by a sperm and you can get pregnant.

The symptoms of ovulation usually vary from woman to woman and from one menstrual cycle to the next. However, minor pelvic pain is often a common symptom occurring before or during ovulation. The discomfort may last for a few moments, but some women experience these sensations for a while. You also may feel a heaviness in your lower abdomen before ovulation.

Ovulation can be painful. Some women experience pain in their abdominal and pelvic areas during ovulation. The discomfort can last from several minutes to hours and the sensation can range from mild to severe. In some cases, you may notice slight vaginal discharge or spotting. Some women may suffer from nausea when the pain is serious. In most cases these unpleasant sensations are normal. However, you should call your doctor if you experience pain when urinating, fever, vomiting, burning of the skin at the site of the pain, or if your pain lasts longer than a day.
