How to calculate the dangerous period and safe period of menstruation

The safe menstruation period can be calculated to prevent the chance of pregnancy from becoming greater. Therefore, we should pay attention to record our safe menstruation period at ordinary times. Under normal circumstances, girls' menstrual cycles are stable, without any abnormalities such as delays or advances. At this time, the safe menstrual period is easier to calculate. Many people ask, how to calculate the safe menstrual period? In fact, not everyone wants to get pregnant. If you don't want to have a baby, you should take preventive measures. In addition, you should calculate your ovulation period and safe menstruation period.

How to calculate the dangerous period of pregnancy and the safe period of menstruation?

There are three main ways to calculate the safe menstrual period: the calendar method, the ovulation temperature method, and the observation of female secretions. Calendar method: Normal women of childbearing age have a menstrual period every 28 days. From the beginning of menarche to the first day of menarche of the next menarche, it is called a physiological cycle. If the menstrual cycle has always been regular, ovulation may be on the 14th day before the next menarche. After the egg is released, it can survive for about 2 to 5 days, and the male sperm can survive for 1 to 3 days after entering the female reproductive system. Therefore, it is easy to get pregnant if you have sex 3 days before ovulation and 5 days after ovulation! The rest of the time is relatively safe, which is what we often call ovulation period.

Ovulation temperature method: Ovulation temperature refers to the body temperature of a normal person after waking up in the morning. It is generally the lowest body temperature of the day. For women of normal childbearing age, their body temperature rises immediately after ovulation and continues until the beginning of the next menstrual cycle. Use the trend of a woman's body temperature during ovulation to find her ovulation period, and abstain from sexual intercourse 3 to 4 days before and 5 to 7 days after.

Observation of female secretions: Observation of female secretions is also a common way to find the safe period of menstruation. Female secretions change regularly with the different stages of the menstrual cycle. During ovulation, the amount of mucus increases, the female vagina feels damp and cold, the mucus becomes clear, and the mucus can be drawn into metal threads, up to 10 centimeters long. The last day this type of mucus lasts is usually the ovulation period. No sexual intercourse during the first 3-4 days and the last 5-7 days.

In fact, after the egg cell is discharged from the ovary, it can survive in the fallopian tubes for 1 to 2 days, waiting for fertilization, and the male sperm can maintain fertilization ability for 2-3 days in the female reproductive system. Therefore, it is very easy to get pregnant by having sex a few days before and after the egg cell is discharged, and this period of time is also known as the dangerous period of pregnancy. We also use the ovulation period as the standard, and include a few days before and after the ovulation period as the dangerous period of pregnancy. To be on the safe side, we call the 5 days before and after the ovulation period, a total of 10 days within the ovulation period, the ovulation period. If you want to calculate the ovulation period, learning to test is also a good method.

The way to test the dangerous period of pregnancy is, for example, a woman's menstrual cycle is 28 days, and the first day of menarche this time is December 2nd, then the next menarche will be on December 30th (December 2nd plus 28 days), and then subtract 14 days from December 30th, then 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.
