How to calculate the safe menstrual period for girls? The calculation method of the safe menstrual period for girls is as follows:

1. Calendar Method

If the menstrual cycle is always regular, ovulation may occur on the 14th day after the onset of menstruation. After the egg is released, it can survive for about 2-5 days, and the sperm can survive for 1-3 days after entering the female reproductive tract. Therefore, abstaining from sexual intercourse 3-4 days before ovulation and 5-7 days after ovulation can avoid pregnancy.

For a woman with a regular menstrual cycle, the time of ovulation is basically stable. Having sexual intercourse during the safe period to achieve the purpose of contraception is called the safe period contraception method. This method is not suitable for young people because they cannot have sexual intercourse more than once a week. This method is suitable for middle-aged people.

2. Basal body temperature method

Basal body temperature refers to the body temperature of a healthy person after waking up in the morning. It is generally the lowest body temperature of the day. For women of normal childbearing age, body temperature rises immediately after ovulation and continues until the start of the next menstrual cycle. Use the changing pattern of a woman's basal body temperature to find her ovulation period and abstain from sexual intercourse 3-4 days before and 5-7 days after.

3. Observation of changes in vaginal secretions

Women's vaginal secretions change regularly during the different stages of the menstrual cycle. During ovulation, the amount of mucus increases, the vagina feels damp, the mucus becomes clear, and the mucus can be stretched into threads, up to 10 cm long. The last day this mucus lasts is generally the ovulation period. No sexual intercourse during the first 3-4 days and the last 5-7 days.

Safe period sexual intercourse is suitable for people with normal menstrual cycles, couples who often live together, and can master and strictly abide by the safe period. Couples who do not live together often, women who have given birth or miscarriage, women who have changes in their mental state, living environment and health, and women who cannot master the safe period, and newlyweds who are emotionally excited and have strong sexual desire are not suitable for safe contraception.

It should be noted that women’s safe period is mainly calculated based on ovulation period and menstrual cycle, but it does not mean that women will not get pregnant during the safe period. There may be objective factors that lead to pregnancy or even infertility.
