How to do contraception during the safe period

The so-called female safe period for contraception is to measure the ovulation date of women through some methods. The date of female ovulation is related to her own body. Generally, there is no special feeling during ovulation. Some female friends will have abdominal pain, breast tenderness and other symptoms. Missing the safe period for contraception will greatly increase the success rate of contraception. It is also welcomed by many families. Let’s talk about it below.

The method of calculating ovulation based on the menstrual cycle is also called the calendar method. Both menstruation and ovulation are affected by endocrine hormones from the pituitary gland and ovaries and show cyclical changes. The length of their cycles is the same, both occurring once a month, and ovulation occurs between two menstrual periods. Women's menstrual cycles vary in length, but the interval between ovulation and the start of the next menstruation is relatively fixed, usually around 14 days. Based on this relationship between ovulation and menstruation, the ovulation period can be calculated according to the menstrual cycle. The calculation method is to count from the first day of the next menstrual period, and count down 14 days or subtract 14 days to get the ovulation day. The ovulation day and the 5 days before and 4 days after the ovulation day are called the ovulation period. This is the theoretical basis of the rhythm method of contraception. For example, a woman's menstrual cycle is 28 days, and the first day of this menstruation is December 2nd. Then the next menstruation will be on December 30th (December 2nd plus 28 days). Subtract 14 days from December 30th, and December 16th is the ovulation day. The ovulation day and the 5 days before and 4 days after it, which is December 11th to 20th, is the ovulation period. Except for the menstrual period and ovulation period, the rest of the time is the safe period. There is no need to use any contraceptive drugs or tools during sexual intercourse during the safe period.

To calculate the ovulation period using this method, you must first know the length of your menstrual cycle in order to calculate the start date of the next menstrual period and the ovulation period. Therefore, this method is only suitable for women with normal menstrual cycles. For women with irregular menstrual cycles, it is impossible to calculate the date of the next menstrual period. Therefore, it is impossible to calculate the ovulation day and ovulation period.

Therefore, it is a very good method to use contraception during the safe period. During this period, men and women do not need to use contraceptive tools when having sex, which improves the quality of sex life for men and women. However, it should be noted that sometimes the date of female ovulation is related to her own physical and mental factors, so there may be errors.
