Ovulation refers to the period of time in a woman’s menstrual cycle when eggs are released from her body. For many women, calculating ovulation is an important step in pregnancy planning. However, for women with less regular menstrual cycles, calculating ovulation can be difficult.

In addition to calculating ovulation, there are a few other ways to help a woman predict when her future husband may be within her ovulation period. For example, women can predict ovulation by measuring their body temperature. Starting on the 14th day of the menstrual cycle, a woman's body temperature will begin to rise and continue until the 16th day of the menstrual cycle. If a woman's temperature rises by 0.5 degrees or more at this time, she may be ovulating.

A woman can also predict ovulation by observing her appetite and energy. Between days 13 and 16 of the cycle, women may feel more tired and have an increased appetite.

While calculating ovulation may not be very complicated, it's important for those hoping to get pregnant to know how to calculate it. At the same time, women can also use other methods to predict that their future husband may be within her ovulation period, so as to better seize this opportunity.
