Giving birth is a woman’s bounden duty. The onset of menstruation means that a woman has entered the childbearing period. Normal menstruation for women of childbearing age is relatively regular, usually once a month. The period from the end of the last menstrual period to the first day of the current menstrual period is called a menstrual cycle. From the perspective of contraception, a menstrual cycle can be divided into a safe period before ovulation during the menstrual period. Ovulation period and safety period after ovulation. Women in Ruijin who have regular menstrual periods usually have a menstrual period of about 2 to 7 days. The rest is the safety period and ovulation period. So what is the relationship between the safety period and the short term of ovulation?

What are the safe period and ovulation period?

Ovulation generally occurs once in a menstrual cycle. For normal women of childbearing age, the ovulation day is about 14 days before the next menstrual period. Affected by the survival time of sperm in the body and the fertilization ability of the egg. The ovulation period generally refers to the ovulation day, the five days before the ovulation day, and the four days after the ovulation day. The safety period, the safety period is divided according to the ovulation period, and can be divided into the safety period before ovulation and the safety period after ovulation. The safety period before ovulation is after the menstruation, well, the ovulation period starts from the first day. The time before ovulation is called the safety period before ovulation. The safety period after ovulation refers to the period from the day before the next menstrual period to the ovulation period. Because normal women of childbearing age will only ovulate once a month, and ovulation will be affected by many factors. Therefore, the safety period after ovulation is safer than the safety period before ovulation.

What is the relationship between ovulation period and safety period?

The safe period changes with the ovulation period.

First of all, the menstrual cycle can be divided into the menstrual phase, the follicle maturation phase, the ovulation day, and the luteal phase. The luteal phase is about 14 days. For women with normal fertility, this time is fixed, so the safety period after ovulation generally does not change. Finding the correct ovulation day can more accurately confirm the safe period. First of all, for women who have very regular menstruation every month, the ovulation day is generally fixed at about 14 days before menstruation. Such women's safe period and ovulation period are relatively stable. Secondly, for women with abnormal menstruation, the menstrual cycle is unstable and the number of menstrual days is different each time. The ovulation period will vary greatly, and the safety period before ovulation is not safe. You can rely on basal body temperature and ovulation test strips to detect ovulation. Generally, the basal body temperature is relatively low before ovulation, and the luteal phase body temperature will rise after ovulation. If the ovulation test paper is close to the parallel bars, it means ovulation is about to occur. After using the ovulation test paper and basal body temperature to determine ovulation, the safe period after ovulation can be determined.

The safe period will be affected by the ovulation period, and the safe period is not necessarily safe. Therefore, if you do not plan to get pregnant, it is best to take safety measures every time you have sex.
