Ovulation refers to the date when an egg is released during a woman's menstrual cycle, usually about 14 days before the next menstrual period. If you want to get pregnant, it's important to know how to predict ovulation.

However, different people's menstrual cycles are different, so it is impossible to accurately predict which day is ovulation. If you want to determine your ovulation period, you can observe your menstrual cycle and calculate your ovulation period.

The calculation method is: starting from the 14th day of the menstrual cycle, every 2 days is a cycle until the 19th day of the menstrual cycle. In this way, you can calculate the days before and after your ovulation period. If the menstrual cycle is longer, the calculation time may need to be extended.

In addition to calculations, there are tools you can use to predict your own ovulation. For example, you can use a thermometer to measure your basal body temperature to determine whether your body temperature is at a high level. You can also use some online tools to predict your ovulation period. These tools usually provide some algorithms and suggestions to help you better understand your menstrual cycle and ovulation period.
