Ovulation refers to the period when hormone levels in a woman's body reach their peak, and it is also one of the important periods for women to become pregnant. During this period, a woman's body undergoes a series of changes that are critical to women's reproductive health and pregnancy.

In addition to changes in the reproductive organs, women experience a range of physical symptoms during ovulation. For example, you may experience mild headaches, low back pain, or mood swings. These symptoms are usually temporary and do not last long.

In addition, a woman's hormone levels also change during ovulation. After the egg is released from the ovary, the ovary will begin to secrete large amounts of estrogen and progesterone, and the levels of these hormones will reach a peak. Changes in these hormone levels are critical to women's reproductive health and pregnancy.

Overall, the changes a woman's body undergoes during ovulation are critical to women's reproductive health and pregnancy. If a woman wants to get pregnant, it is recommended to measure her body temperature regularly, observe body changes, and take appropriate measures near the ovulation period to increase the chance of pregnancy.
