The ovulation curve chart is one of the important tools for assessing female fertility. Women experience a series of physiological changes every month, including menstrual cycle, quantity, body temperature, and hormone levels in the body. These changes may affect a woman's fertility. Therefore, understanding the ovulation curve can help women better predict their possible chances of pregnancy.

A woman's menstrual cycle is usually divided into two phases, the previous cycle and the following cycle. In the days leading up to the start of your cycle, a woman's body temperature will rise as her body prepares for pregnancy. In the days after your cycle ends, a woman's body temperature will drop, which is her body's sign of ending her cycle. This process usually lasts for several days and is known as ovulation.

During ovulation, a woman's body temperature will rise to about 37 degrees Celsius, which is a sign that her body is preparing for pregnancy. This process usually lasts several hours and is known as the danger period. If a woman is fertilized during the risk period, she may become pregnant.

A woman's menstrual cycle and changes in hormone levels in her body may cause discomfort such as headaches, nausea, and breast pain. Therefore, women should avoid overexertion and maintain a healthy diet and sleep in the days before and after their cycle. If a woman conceived during the risk period, she should continue to monitor changes in her body temperature and follow her doctor's recommendations for a pregnancy test.
