28 days of menstrual period and ovulation period

The 28-day period refers to the 28-day menstrual cycle of a woman, and the ovulation period refers to the date when the egg is released. A woman's eggs wait for fertilization in the ovary, which usually takes about 4-5 days. During this time, the woman's body temperature will rise and her body will begin to secrete mucus. In the days after ovulation, a woman's body temperature will drop and her mucus will decrease. This is an important period for women to become pregnant.

So, how to determine the 28th day of menstruation and ovulation? This can be determined by measuring basal body temperature and observing body changes. Basal body temperature refers to the body temperature measured when you wake up in the morning and do not perform any activities. Women can learn about their menstrual cycle by recording their basal body temperature, and determine the 28 days of menstruation and ovulation.

In addition to measuring body temperature, women can also determine the 28 days of menstruation and ovulation by observing changes in the body. For example, women may notice that their breasts become more tender during ovulation and their breasts may feel slightly swollen. In addition, women can also observe their sexual desire and appetite. If these changes occur between the 28th day of menstruation and the ovulation period, then this may be pregnancy.
