Experts teach you how to accurately calculate women’s safe period

　　Ovulation period: menstrual cycle method, basal body temperature method and ovulation test paper test method

　　Ovulation period

　　The method of calculating ovulation based on the menstrual cycle is also called the calendar method. Both menstruation and ovulation are affected by the endocrine hormones of the pituitary gland and ovaries and show cyclic changes. The length of the two cycles is the same, one cycle per month, and ovulation occurs in the middle of two menstruation.

　　Ovulation test strip test method

　　Ovulation test strips are not just for measuring ovulation day! normal female , if you get pregnant this month, then the ovulation test paper this month will definitely show two positive results, or even a strong positive result! The first time is when you ovulate, which is in the middle of a menstrual cycle, and the other time is within 7-10 days after intercourse.

　　If the test result is negative, you can test once every other day. If there is a weak positive, you need to test once a day. If there is a strong positive (that is, when the test line and the control line are both obvious), it means ovulation will occur within 24-48 hours. Generally, strong yang will last for 2 days. When the strong yang turns to yin, it means ovulation has occurred.

　　Work out the date of your next menstrual period. Therefore, it is impossible to predict the ovulation day and period.

　　Women's menstrual cycles may be long or short, but the interval between the day of ovulation and the start of the next menstrual period is relatively fixed, generally around 14 days. Based on the relationship between ovulation and menstruation, the ovulation period can be calculated based on the menstrual cycle. The calculation method is to count from the first day of the next menstrual period, counting down or subtracting 14 days is the ovulation day. The ovulation day and the 5 days before and 4 days after the ovulation are called the ovulation period. This is the theoretical basis of the safe period contraceptive method.

　　For example, if a woman's menstrual cycle is 28 days, and the first day of this menstrual period is December 2, then the next menstrual period will be on December 30 (December 2 plus 28 days), and then subtract 14 days from December 30, then December 16 is the day of ovulation. The ovulation day, 5 days before and 4 days after it, that is, December 11-20 is the ovulation period.

　　To use this method to calculate the ovulation period, you must first know the length of the menstrual cycle before you can calculate the start date and ovulation period of the next menstrual cramp, so it can only be applied to women with normal menstrual cycles.

　　The so-called menstrual cycle is: the first day of menstruation is counted as the first day of the cycle, and it lasts until the day before the next menstruation. It is called a menstrual cycle, generally speaking, it is about 26-35 days. Normal women of childbearing age have menstruation once a month. The period from the beginning of this menstrual period to the first day of the next menstrual period is called a menstrual cycle. For example, from the perspective of contraception, each menstrual cycle of a woman can be divided into the menstrual period, the ovulation period (that is, the dangerous period) and the safe period.

　　cyclical changes

　　The basal body temperature of normal women of childbearing age changes cyclically, just like the menstrual cycle. This change in body temperature is associated with ovulation. Under normal circumstances, a woman's basal body temperature is low before ovulation and rises after ovulation.

　　The temperature should be measured as soon as you wake up every morning. You cannot take it after you get up. You should take it as soon as you wake up. Try to keep your body still and don't talk. Take your temperature as soon as you wake up. Do this every day and observe dynamically.

　　When the body temperature suddenly drops one day and then jumps up to 0.3-0.5 degrees the next day, it means that ovulation is about to happen or is ovulating. In short, it is a high-risk period.
