A woman's normal ovulation period refers to the time frame during which a woman's eggs are released from the ovaries and wait in the fallopian tubes for fertilization. During this time, a woman's immune system begins to release a chemical called interleukin-1 (IL-1), which promotes the maturation and movement of a woman's eggs. At the same time, the female reproductive organs will also undergo a series of changes to adapt to the discharge and fertilization of eggs.

In addition to normal ovulation, a woman's body goes through a series of changes to adapt to fertilization and childbirth. These changes include:

- Egg maturation and movement: During ovulation, a woman’s egg begins to mature and gradually moves into the fallopian tube, waiting for fertilization.

- Fertilized egg implantation: When the sperm and egg meet, the fertilized egg will implant in the woman's uterus and start a new journey of life.
