It seems likely that menstruation is causing you pain, not ovulation. Every menstruation is more or less painful but during painful menstruation (dysmenorrhea), the pain is so severe that it disables a woman to perform her everyday activities. Dysmenorrhea can be either "primary" or "secondary".


Primary, or idiopathic, dysmenorrhea has an unknown cause and is typical for healthy, young women. It is believed that during menstruation there are higher amounts of prostaglandin that can cause uterine contractions. Secondary, or symptomatic, dysmenorrhea is caused by other diseases such as: premenstrual syndrome (PMS); stress and anxiety; endometriosis; pelvic inflammatory disease (PID); sexually transmitted diseases; fibroids; ovarian cysts; intrauterine Device (IUD) etc.


Primary dysmenorrhea is usually treated with non-steroid anti-inflammatory drugs (NSAID): aspirin, paracetamol, ketoprofen, diclofenak, ibuprofen etc.


Alternative (home) treatment may include: applying a heating pad to your lower abdomen (below your belly-button); taking warm showers or baths; drinking warm beverages; performing a light, circular massage with your fingertips around your lower abdomen; walking or exercising regularly, including pelvic rocking exercises; starting a diet that is rich with complex carbohydrates such as whole grains, fruits, and vegetables, but low in salt, sugar, alcohol, and caffeine; eating light but frequent meals; practicing relaxation techniques like meditation or yoga; trying vitamin B-6, calcium, and magnesium supplements, especially if your pain is from PMS, and keeping your legs elevated while lying down or lie on your side with knees bent.


In secondary dysmenorrhea, the primary disease has to be treated.


You can visit a gynecologist to identify what type of dysmenorrhea you may be experiencing.
