There are many ways to calculate ovulation, but the most common method is to use a formula. The following is a commonly used formula for calculating ovulation:

For example, if the cycle is 28 days, then the risk period should be the cycle minus 14 days to get 14 days, plus the day after the cycle date, that is, 14 days + 28 days = 42 days.

This formula only provides a reference, because everyone's cycle is different, so it needs to be adjusted appropriately according to personal circumstances. In addition, this formula is not suitable for all situations because it only takes into account the period and date and does not take into account other factors such as temperature, diet and exercise.

Calculating ovulation is not an important thing because it does not guarantee the quality of fertility. If planning a pregnancy, please consult a doctor or professional advisor for more accurate advice.
