Girls' safe period and dangerous period

If both men and women are not sure whether they want to have children, they should try to avoid having sex during the dangerous period, because if they have sex during the dangerous period without taking relevant contraceptive measures, it is easy to get pregnant. A woman's body is mainly divided into menstrual period, safe period and dangerous period in a month, but most women don't know how to distinguish between the safe period and the dangerous period. The following article explains to women how to calculate the safe period and dangerous period.

Three methods to calculate the safe period

1. Calendar method

First, understand your menstrual cycle and calculate your ovulation period on the calendar. The other dates excluding the ovulation period and menstruation period are the safe period.

For example, if your menstrual cycle is 30 days and your menstrual period is 5 days, and your last menstrual period was from December 1 to December 5, then the next one will be December 31. The ovulation date is 14 days before the next menstrual period, which is December 17. The ovulation period is 5 days before the ovulation date and 4 days after the ovulation date, which is December 12 to December 21. Then the safe period is December 6 to December 11 and December 22 to December 30.

This method is suitable for women with regular menstrual cycles, so its accuracy rate is relatively low. It is best to remain objective when choosing it. If your menstrual cycle is irregular, you can choose the following two methods.

2.Basal body temperature method:

The progesterone secreted by the female body during ovulation will stimulate the hypothalamus, causing the body temperature to continue to rise, and it will not return to normal until the next menstruation comes. Therefore, you only need to measure the basal body temperature to find the ovulation day. The 5 days before and 4 days after the ovulation day are the ovulation period. Excluding the menstrual period, the rest of the time is the safe period.

However, although basal body temperature is relatively accurate, it is difficult to measure. Emotional factors, staying up late, physical condition, etc. can cause changes in body temperature, making it impossible to determine the ovulation day. Therefore, you must be careful when using this method.

3. Uterine mucus method

When ovulation arrives, hormones in women's bodies rise, and the amount of mucus in the vagina increases, similar to egg white. When the mucus becomes thicker and the amount decreases to nothing, it means that ovulation is over. The safe period basically begins 3 days after the mucus disappears.

In addition, it is best to follow the daytime mucus, as it may be affected by sperm remaining in the vagina at night. This method is rather troublesome and should not be believed blindly. Women who want to get pregnant can use it to find their ovulation period, which can help them get pregnant. If they want to avoid pregnancy, it is best to use other methods for comprehensive judgment.
