How to calculate the safe physiological period for women

Female friends must know the safe physiological period, because by understanding and calculating these safe periods, you can know exactly what time period can better increase the chance of conception, and after understanding the safe period, it can also be used as a contraceptive method.

1. Safe period contraception is one of the contraceptive methods that many people are accustomed to using. How to calculate the safe period? Simply put, the rule of the safe period is "seven before and eight after", which means that the first seven days and the last eight days of menstruation are safe periods. The so-called seven before and eight after is calculated from the first day of menstruation. Although it is best to avoid sexual intercourse during the menstrual period, the menstrual period is also included in the safe period. A woman's menstrual cycle is generally about 28 days, and each menstrual cycle is divided into the menstrual period, ovulation period and safe period.

2. The safe period is "seven before and eight after", so the safe period is divided into the safe period before ovulation and the safe period after ovulation. A woman's ovulation date is generally about 14 days before the next menstrual period. The period from the end of menstruation to three days before ovulation is the safe period before ovulation.

3. The safe period after ovulation is from the first day after the end of ovulation to the day before the next menstruation. If a woman has a regular menstrual cycle, her ovulation time is basically stable, so it is easy to calculate the safe period and have sexual intercourse during the safe period to achieve the purpose of contraception. Moreover, there is no need to use any contraceptive drugs or tools during sexual intercourse during the safe period.

4. Using this method of contraception actually has certain risks, because if a woman's ovulation period is advanced or delayed, the safe period becomes uncertain and there is still a possibility of pregnancy.
