Calendar-based contraceptive methods contraception is easy to fail Why is Calendar-based contraceptive methods contraception unreliable

Calendar-based contraceptive methods contraception is a kind of physiological contraception method. Sexual life can be carried out in a normal state to obtain satisfactory sex appeal. However, if not strictly grasped or used improperly, it is easy to fail.

When using Calendar-based contraceptive methods contraception, first of all, we should accurately measure the ovulation period. At present, the three methods for determining the ovulation period have their own advantages and disadvantages: the calendar method can be used to calculate the Calendar-based contraceptive methods of the ovulation period, before ovulation, and after ovulation. However, it is only applicable to women with normal menstruation. Due to changes in the environment and feelings, ovulation will be advanced or delayed. Therefore, the basic body temperature measurement method can measure the ovulation date and the Calendar-based contraceptive methods after ovulation, but it cannot predict the Calendar-based contraceptive methods before ovulation. This method is troublesome and strict. If the body temperature is not measured according to the regulations, the ovulation date cannot be measured correctly: the cervical mucus observation method can measure the Calendar-based contraceptive methods before and after ovulation, with high accuracy, But users must receive training and complete mastery before they can use it. The combination of the three methods of contraception in the Calendar-based contraceptive methods can avoid the length and achieve greater effect.

Firstly, the basic body temperature measurement method. Basic body temperature refers to the temperature of a healthy person after waking up in the morning, usually the lowest temperature of the day. For women of normal childbearing age, the body temperature rises immediately after ovulation and continues to the next Menstrual cycle. Using the pattern of changes in female basal body temperature, find the ovulation day and refrain from sexual intercourse for 5-7 days after 3-4 days.

Next is the calendar method. For example, the Menstrual cycle is always accurate. Ovulation may take place on the 14th day after menstruation. About 2-5 days after ovulation, sperm can survive for 1-3 days after entering the female reproductive tract. Therefore, no sexual intercourse 3 to 4 days before ovulation and 5 to 7 days after ovulation can avoid pregnancy

For women with regular Menstrual cycle, the ovulation time is basically stable. Making love during the safe period to achieve the purpose of contraception is called Calendar-based contraceptive methods contraception. This method is not suitable for young people. Because the frequency of sexual intercourse cannot be separated by about a week. This method is suitable for middle-aged people.

Finally, observe the changes of Vaginal discharge. Women's Vaginal discharge change regularly with the different periods of the Menstrual cycle. During ovulation, there is more and more mucus, and there is a sense of dampness in the vagina. The mucus becomes clear and can be stretched, up to 10 centimeters in length. The last day of this mucus persistence is usually the ovulation period. Not having sex for the first 3-4 days and the next 5-7 days.
