The ovulation period in girls refers to the period of time when eggs mature and are released in a woman's body. It usually occurs during a woman's menstrual cycle and lasts about 4-5 days. During this period, the female reproductive organs will begin to undergo a series of changes to ensure that the egg can be released smoothly.

- Increase in body temperature: During ovulation, a woman's body temperature will rise by 0.5 to 1 degree Celsius as the body adjusts to release the egg.

- Increased appetite: During ovulation, women may feel hungrier and have an increased appetite.

- Energy: During ovulation, women may feel more energetic, think clearly, and be emotionally unstable.

The ovulation period for girls is a very important period, because during this time, the female egg matures and is released, which is an important period for female fertility. If a woman wants to get pregnant, she should try to have intercourse during the ovulation period to ensure that sperm can enter the female's reproductive organs and combine with the egg.
