Abdominal pain is a common symptom during ovulation, but it does not necessarily mean there is something wrong. In many cases, this pain is a normal physiological response. However, if the pain is severe or lasts for a long time, you may need to seek medical attention to rule out other health problems.

Some possible reasons include:

1. Ovarian rupture: This is a common ovulation symptom that often results in abdominal pain and bleeding.

2. Infection: If abdominal pain lasts for a long time or is very severe, it may be due to a bacterial or viral infection.

3. Other diseases: Intestinal diseases, such as colitis or Crohn's disease, may also cause abdominal pain and distension.

4. Malnutrition: Abdominal pain and distension may also occur if the body lacks adequate nutrition.

If you experience abdominal distension and pain, it is recommended to seek medical attention promptly to diagnose and treat any possible problem. The doctor may perform an ultrasound or other tests to determine the cause of the pain and prescribe appropriate medications to relieve symptoms. At the same time, eating a healthy diet and getting enough rest are also important measures to relieve abdominal pain.
