About this symptom

Ovulation Pain

Ovulation pain, or "mittelschmerz" (a German word meaning middle pain) affects approximately 20% of women. It is described as sharp pains followed by a dull nagging ache that can last a day or so around mid-cycle. For some women the pain can be severe enough to interfere with daily life. It usually lasts about 6 to 8 hours, but can last up to 48 hours for some. It is normal and quite common, painful ovulation is rarely serious.
