Ovulation refers to the time when a woman's egg is released from the ovary, usually between the 14th and 16th days of the menstrual cycle. For many women, this process is a monthly one and is very important. However, not all women will release an egg on that day, depending on a variety of factors, including health, menstrual cycle, and the size and function of the ovaries.

First, we need to understand how basal body temperature works. Basal body temperature refers to the body temperature measured when you wake up in the morning before doing any activities. In general, a woman's body temperature changes with her cycle, especially during ovulation. When the body temperature rises by about 0.5°C, it means that a woman is releasing eggs.

Therefore, we can predict when an egg will be released by measuring basal body temperature. Typically, a woman's body temperature begins to rise between the 14th and 16th days of her menstrual cycle. We can monitor this process by taking body temperature every day and recording the results.

In addition to measuring basal body temperature, we can also look at other cues in the menstrual cycle to predict when an egg will be released. For example, women may experience symptoms of AA (day AA) between days 10 and 14 of their menstrual cycle, which usually means they will release an egg on this day. In addition, a woman's physical condition and emotional state may also have an impact on egg release.
