About one in five women experience pain and discomfort during ovulation. The duration of the pain varies from one woman to the next, but ranges from a few minutes to 48 hours. In most cases, ovulation pain doesn’t mean that anything is wrong.
However, severe pain may sometimes be symptomatic of gynaecological conditions including endometriosis, which was the cause for painful ovulation and periods I experienced for nearly a year before I decided to seek help from my doctor and gynaecologist.
I would recommend that you consult with your doctor/gynaecologist if your ovulation pain lasts longer than three days or is associated with other unusual menstrual symptoms, such as heavy bleeding.
Good luck :)
