How to calculate ovulation day?

Generally, ovulation occurs approximately 14 days before the next menstrual period in a woman's menstrual cycle, which means it is about 14 days from the last day of the menstrual period to the ovulation day under normal circumstances. To calculate the ovulation day, you can use the following method:

Calculate the date of the next menstrual period: Based on the number of days between each menstrual cycle, add the number of days to the last day of the period to get the date of the next menstrual period.

Calculate the ovulation day: Subtract 14 days from the date of the next menstrual period to get the date of the ovulation day.

However, this method only provides an approximate estimate, and if there is a plan for conception or contraception, it is recommended to use other methods as well.

What is the fertile period (also commonly known as the "dangerous period")?

The fertile period, also commonly known as the "dangerous period," refers to the five days before and four days after ovulation, as sperm can survive in the body for up to five days. Of course, the "dangerous period" is only relevant to individuals who do not have plans for pregnancy. For those who are trying to conceive, this period is considered the golden opportunity.
