Ovulation refers to the process in a woman’s body when eggs are released from the ovaries and enter the fallopian tubes to wait for fertilization. This process usually occurs on the 14th day of a woman's menstrual cycle, also known as the "dangerous period" or "fertile period."

So, how do you accurately predict ovulation so you can get pregnant at the best time? Let’s get into some science and tricks.

First, we need to understand the female cycle. Generally speaking, the female cycle is divided into 4 stages: pre-puberty, teenage years, adulthood and menopause. In adulthood, a woman's menstrual cycle typically lasts 28 days, but some may have shorter or longer cycles.

Second, we need to understand the female egg. Women produce eggs once a month, and these eggs usually begin to be released from the ovaries on day 14. The lifespan of an egg is usually 2-3 days until fertilized by sperm.

Finally, we need to understand how to predict ovulation. Generally speaking, ovulation can be predicted by the following methods:

1. Observe cycles: By observing women’s cycles, you can learn about their approximate date and time of birth.

2. Measure basal body temperature: Measuring basal body temperature can help women accurately predict ovulation. When women wake up every morning, measure their oral temperature, and then record the temperature change until the body temperature rises by 0.3-0.5 degrees Celsius.

3. Use prediction tools: There are many online tools that can help women predict ovulation, such as the "Danger Period Calculator" or the "Predictive Temperature Chart."

To sum up, predicting ovulation requires some science and skills, but through these methods, women can better understand their bodies and fertility, and thus better arrange their fertility plans.
