A woman's ovulation date is generally about 14 days before her next menstrual period. Counting from the first day of the next menstrual period, the 14 days backward or subtracting 14 days is the ovulation day, and the ovulation day and the first 5 days and the next 4 days together are called ovulation. For example, if a woman's menstrual cycle is 28 days, and the first day of this menstrual period is on December 2, then the next menstrual period will be on December 30 (December 2 plus 28 days), and then subtract 14 days from December 30, then December 16 is the day of ovulation.
Ovulation is the day of ovulation and 5 days before and 4 days after, that is, December 11-20. Except for the menstrual period and ovulation, the rest of the time is the safe period.

The estimation of the safe period is related to the ovulation period and the menstrual cycle. For women with regular menstruation, the first 7 days and 8 days after menstruation are safe periods, but for women with irregular menstruation, there is no way to calculate the safe period.
1.If a woman's menstruation is more regular every month, the menstrual cycle is about 28 days, ovulation is generally about 14 days before the next menstruation, about 5 days before the ovulation period is the fertile period, except for these 8-9 days, the rest of the time belongs to the safe period, that is, it is not easy to get pregnant.
2.If a woman's menstruation is not particularly regular, and often occurs early or postponed, then the ovulation period is not fixed, so there is no way to calculate the safe period, and other contraceptive methods can be used to prevent pregnancy.
Women's menstruation has a certain relationship with emotions and environmental influences, so the method of contraception during the safe period is not particularly safe, and it is recommended to take a relatively safe contraceptive method to avoid unwanted pregnancy.

After a woman reaches puberty, the soybean oil ovulation period and the safe period are every month. Ovulation, safe period, how to calculate?
The so-called safe period is 14 days before the day of your period, for example, if you come on the 30th, then push forward 14 days from the 30th, that is, the first few days before the 16th is your safe period.
To put it simply: if women's menstruation comes on the 1st, then the 1st-10th, 20th-30th are the so-called safe periods, and the ovulation period is the 15th, but they are pushed for 5 days each for more safety. However, it is not absolutely accurate and varies from individual to individual.
The safe period is relative, it is within 1-10 days after menstruation, and it is 1-12 days written in the book, so it is two days less for safety. It is only relative to the safe period from 22 days after menstruation to the day before menstruation.
The safe period is further divided into the pre-ovulation safe period and the post-ovulation safe period. The period from the day of menstruation to the day before the start of ovulation is the safe period before ovulation. The safe period after ovulation is from the first day after ovulation ends to the day before the next menstrual period. >>>More
