The ovulation period refers to the middle of each month for women, that is, between the 14th and 21st days of menstruation. Knowing how to calculate ovulation is an important issue for many women as it can help them better plan their pregnancy.

However, for many people, calculating ovulation is not an easy task. Even for some women, they may not be able to accurately calculate when they ovulate. In this situation, some women may choose not to plan a pregnancy or use other forms of birth control until they can determine whether they are ready to become pregnant.

While calculating ovulation isn't always easy, there are ways to help women better plan their pregnancies. First, women can record their menstrual cycles and predict their ovulation based on their menstrual cycles. Secondly, women can observe their own body reactions, such as increased body temperature, increased appetite, high energy, etc. These reactions can usually indicate a woman's ovulation period. Finally, women can also use some fertility prediction tools to help them better plan their pregnancies.

While calculating ovulation isn't always easy, there are ways to help women better plan their pregnancies. No matter which method women choose, they need to remember that calculating ovulation is not guaranteed to be 100% accurate, so women should decide how to plan their pregnancy based on their specific circumstances.
