What is the safe period for girls?

When is the safe period for women? A woman's menstrual cycle can generally be divided into three parts: ovulation period, physiological period and safe menstruation period. Regardless of whether she wants to get pregnant or uses the safe period contraceptive method, grasping the time of the safe menstruation period is beneficial to pregnancy and contraception. So what is the safe menstruation period?

When is the safe period for women?

Women's safety period is generally divided into two stages: before ovulation and after ovulation. From the day before the last menstrual period to the day before the next ovulation is the menstrual safety period before ovulation, and from the last day of ovulation to the day before the next menstrual period is the menstrual safety period after ovulation.

How to calculate the safe period for women

For women with regular menstrual cycles, the safe menstrual period can be calculated according to the “seven before and eight after” period. “Seven before and eight after” refers to the first seven days and last eight days of the menstrual period. Assuming that the menstrual period is 28 days, and the first day of this menstrual period is January 2, then the first day of the next menstrual period is January 30, and then 14 days from January 30, which is January 16, is the ovulation period. The 5 days before and 4 days after the ovulation period add up to the ovulation period, which is January 11-20 for the ovulation period, which is the easiest stage to get pregnant, and the safe menstrual period is the time excluding the menstrual period and ovulation period. Because the ovulation period is very susceptible to the external environment and psychological influence, the safe menstrual period during ovulation may be shortened. Relatively speaking, the probability of pregnancy during the safe menstrual period after ovulation will be lower.

Common questions about rhythm method

In addition to using the menstrual cycle to calculate the safe period, you can also use the ovulation temperature method and secretion observation to calculate the ovulation period. However, the safe menstrual period is not absolutely safe. Even for girls with regular menstrual cycles, the ovulation period may fluctuate to a certain extent, so the calculation of the safe menstrual period may have some errors.
