Pain on one side of the abdomen during ovulation is a common physiological phenomenon that is usually nothing to worry about, but it may also cause discomfort to some women. In some cases, it may be a symptom of a disease, but in most cases, it is a normal physiological response.

However, if the pain is too severe or lasts for too long, or is accompanied by other symptoms such as nausea, vomiting, diarrhea, etc., then you may want to consider seeking medical attention. Some possible illnesses include genital infections, dysmenorrhea, irregular menstruation, etc., which may cause pain on one side of the abdomen.

If you experience pain on one side of your abdomen during ovulation, you can first try to see if the pain lasts for a long time or is too severe. If symptoms persist for a long time or are accompanied by other symptoms, it is recommended to seek medical advice as soon as possible for diagnosis and treatment. Also, if you're considering becoming pregnant, it's a good idea to talk to your doctor first to make sure you're physically fit for pregnancy.
