Is the 9th day of menstruation a safe period?

Is the ninth day of the menstrual period a safe period? Women's ovulation period is generally about 14 days before the next menarche. To be on the safe side, we call the 10 days before and after the ovulation period the ovulation period, and the rest of the menstrual cycle is called the safe menstrual period.

Is the ninth day of menstruation a safe period?

Traditionally speaking, seven days before menstruation and eight days after menstruation are the safe menstrual period for adult women, which is a calculation method used by most people for contraception. However, the safe menstruation period is not absolutely safe. Sometimes women ovulate earlier or later, so the judgment of the safe menstruation period will become invalid. Identifying the safe menstrual period only reduces the chance of pregnancy.

Women's ovulation period is generally about 14 days before the next menstrual period. To be on the safe side, we call the 10 days before and after the ovulation period the ovulation period, and the rest of the menstrual cycle is called the safe menstrual period. The safe menstrual period is divided into the safe menstrual period before ovulation and the safe menstrual period after ovulation. Generally speaking, the safe menstruation period after ovulation is safer than the safe menstruation period before ovulation. This is because some women sometimes affected by environmental damage and mood swings affect the advance of ovulation, so before ovulation safe period will be shortened, but they do not know, so before ovulation safety period is not safe. The ovaries in one menstrual cycle have two eggs in a row opportunity is very rare, that is, after ovulation until the next menstrual menarche before this period of time usually won't happen again the second time of ovulation, so the menstrual safety period after ovulation is relatively safe.

The key to choosing safe period contraception is to measure the time of women's ovulation. During the ovulation period, there is generally no special feeling. Even though some women may have symptoms such as lower abdominal pain, back pain, breast swelling and mood changes, these symptoms are not unique to the ovulation period and cannot be used as a basis for ovulation. Menstrual period and ovulation period change regularly and are closely related to each other. If you understand the changing trends of the two, you can measure the ovulation time indirectly.

How to calculate ovulation period according to menstrual cycle

The method of calculating ovulation according to the menstrual cycle is also called the calendar method. Both menstruation and ovulation are affected by the endocrine hormones of the hypothalamus, pituitary gland and uterus and ovaries and show regular changes. The length of their cycles is the same, both are one cycle per month, and ovulation occurs in the middle of two menstruations. Women's menstrual cycles vary in length, but the time interval between ovulation and the start of the next menstrual period is relatively fixed, usually about 14 days. Based on the relationship between ovulation and menstruation, the ovulation period can be calculated according to the physiological cycle.

The calculation method is to count from the first day of the next menarche, and the last 14 days or minus 14 days is the ovulation period. The ovulation period plus the first 5 days and the last 4 days are called the ovulation period. This is the basic 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 period. The ovulation period, the 5 days before and the 4 days after, that is, December 11-20 is the ovulation period. Except for the menstrual period and ovulation period, the rest of the time is the safe menstrual period. During the safe menstrual period, there is no need to use any contraceptive drugs or contraceptive tools for sexual intercourse.

To calculate the ovulation period using this method, you must first understand the length of your menstrual cycle in order to calculate the start time of the next menarche and the ovulation period. Therefore, it is only suitable for women whose menstrual cycles have always been normal.
