Ovulation budget

A woman's menstrual cycle usually varies from person to person, but most women's cycles last from 28 to 30 days. At the beginning of the cycle, a woman's egg is released from her ovary and waits for 7 to 10 days to be fertilized.

There are many ways to predict ovulation, the most common of which are the basal body temperature method and the calendar method.

The basal body temperature method refers to measuring a woman's basal body temperature and recording it in a table. A woman's basal body temperature typically rises by 0.5 to 1 degree Celsius at the start of her cycle, peaking at around 37 degrees Celsius mid-cycle. If a woman's basal body temperature continues to remain above 37 degrees Celsius in the middle of her cycle, she is likely to release an egg later in her cycle.

The calendar method refers to recording a woman’s cycle and predicting ovulation according to the rules. This method requires women to understand their menstrual cycles and accurately record the time of each cycle. Women usually release their eggs on a certain day mid-cycle, so you can predict that day by recording the time and date of your cycle.

In addition to the above two methods, there are other ways to predict ovulation, such as using the David calendar method, using a thermometer and observing changes in sexual desire.

To summarize, budgeting for ovulation requires accurately recording a woman’s cycle and time, and using a variety of methods to predict it. If couples want to have children, they can plan in advance and have sex on the expected date so that sperm can enter the woman's body in advance to increase the probability of fertilization.
