During ovulation, a woman's body undergoes a series of changes that may cause symptoms. If you're considering pregnancy or are married but don't have children yet, knowing these symptoms can help you better understand your health.

Here are some symptoms you may experience during ovulation:

1. Increase in body temperature: During ovulation, a woman’s body temperature will increase by 0.3-0.5 degrees Celsius. This is because the body is preparing for fertilization and requires a lot of energy to produce more sperm.

2. Increased appetite: During ovulation, women may feel an increase in appetite and want to eat some nutritious food.

3. Increased libido: During ovulation, women may feel an increase in sexual desire and want to have sex.

4. Increased energy: During ovulation, women may feel increased energy, feeling more alert and energetic.

5. Increased vaginal secretions: During ovulation, a woman’s vaginal secretions will increase and become softer and moister in texture.

These symptoms do not necessarily appear during ovulation, but may occur at other times. If you have any concerns, it's best to consult your doctor. In addition, if you are considering pregnancy, it is best to have sex at this time to ensure the quantity and quality of sperm.
