Many cases of accidental pregnancy show that the Calendar-based contraceptive methods is not necessarily safe. For men and women who do not like condoms, this is a frustrating thing. Is there an absolute Calendar-based contraceptive methods during menstruation?

Is there an absolute Calendar-based contraceptive methods?

The absolute Calendar-based contraceptive methods, as the name implies, will not be pregnant if you have unprotected sex during this period. The absolute safety period does not exist, and the safety period can only be said to be relatively safe. It's just a matter of probability, the lower the probability of pregnancy, the safer it is. According to the probability of pregnancy, the Menstrual cycle can be divided into menstruation, Calendar-based contraceptive methods and dangerous period.

First of all, women are generally not pregnant during menstruation, which is a special period for women's body. During this period, women's resistance is weak. During menstruation, the endometrium falls off, blood is discharged, and the cervix is loose. At this time, sexual behavior is vulnerable to the invasion of uterine viruses and bacteria. Sexual behavior in acute cervicitis cases and holidays is very harmful to women, so it is recommended not to have sex on the regular holidays. Making love is not absolutely safe. Because some women with relatively short Menstrual cycle will enter a dangerous period when their menstruation is clean. If their menstruation is delayed for a long time, they will enter a dangerous period of pregnancy when their menstruation is almost finished, so even sexual behavior during the menstrual period may lead to pregnancy.

During the safety period after the next menstruation, due to the influence of environment, pressure, diet and other aspects, ovulation may be advanced, ovulation may be advanced, and the safety period before ovulation will also be advanced, but this advance is difficult to perceive, so the Factor of safety during the safety period after menstruation is not high. Entering the ovulation period, also known as the danger period, there is a high chance of having sexual intercourse before and after ovulation, and the closer the ovulation date is, the greater the chance of pregnancy.

The third is the Calendar-based contraceptive methods after the danger period. Relatively speaking, this period is relatively safe. As long as you decide to ovulate, the farther away from the ovulation day, the safer it will be. Because the number of ovulations per Menstrual cycle is fixed, women will ovulate only once. However, it cannot be said to be 100% safe. Generally speaking, there is no possibility of secondary ovulation, but the possibility of secondary ovulation cannot be completely ruled out.

To sum up, the absolute Calendar-based contraceptive methods does not exist, so we can only say that the Factor of safety is relatively high a few days before the next menstruation. I suggest you take effective contraceptive measures or have sex. In addition to the Calendar-based contraceptive methods method of contraception, there are condom contraception and contraceptive pill contraception. However, it is generally not recommended to use the contraceptive pill as a conventional method of contraception, because "the pill is toxic". It is generally recommended for men to use condoms for contraception.
