It is a common physiological phenomenon for girls to experience abdominal distension and pain during ovulation, especially in the first few days and the last day of ovulation. This phenomenon usually occurs during a girl's menstrual cycle, but some girls may experience discomfort during ovulation.

First, you can try changing your diet. During ovulation, your body needs nutrients more frequently to ensure it is getting enough energy and nutrients. If your diet is too simple or lacks nutrients, it may cause you to feel bloating and pain in your lower abdomen. Therefore, it is recommended that you try to increase your protein, vitamin and mineral intake and avoid eating too many high-sugar and high-fat foods.

Secondly, you can try some simple exercises. Your body may feel more sensitive and tense during ovulation, so some light exercise may help relieve symptoms. For example, you could try exercise such as walking, yoga, or jogging.

Finally, you can try using hot or cold compresses to relieve abdominal distension and pain. If you feel pain in your lower tummy, apply a hot water bottle or ice pack to your abdomen to help relieve pain and discomfort. If you experience severe pain, you can use ice to relieve pain.
