Why is contraception unreliable in the Calendar-based contraceptive methods? Avoid these misconceptions

Both genders often use contraceptive methods in their daily sexual life. For example, wearing condoms, taking oral contraceptives, couples and couples use the method of Calendar-based contraceptive methods contraception. Many people who use Calendar-based contraceptive methods contraceptives must know the first seven and the last eight. So, what exactly is this?

Is it reliable to use contraception before and after the Calendar-based contraceptive methods

The first seven days: This is the first seven days of menstruation, which is a relatively safe post Calendar-based contraceptive methods. Almost no one understands it wrong.

The last 8 days are calculated from the first day of menstruation, not from the end of menstruation. If a woman starts menstruation on December 1st and ends on December 6th, the last eight days are not from December 1st to December 8th, but from the end of menstruation to December 7th to December 14th. In fact, this woman excluded the days of menstruation, and only December 07 and 08 were truly the former Calendar-based contraceptive methods.

If a woman's Menstrual cycle is less than 26 days, generally speaking, the first seven are Calendar-based contraceptive methods, and the last eight are not applicable. Contraception during the safety period is affected by emotion, climate, environment and other factors. Ovulation may be advanced, delayed and increased. Therefore, contraception during the safety period is not absolutely safe, so many women do not recommend using contraception during the safety period alone.

Three common misconceptions about taking contraceptive pills

Misunderstanding 1: Contraceptive pills can increase the risk of cancer

In fact, oral contraceptives can provide additional protection, allowing you to resist the invasion of cancer. Many studies have shown that after taking the contraceptive pill for one year, women's chances of developing cervical cancer are reduced by half; Taking it for more than a year can reduce the risk of ovarian cancer by 40%;

According to a recent statistical data in Taiwan, after taking the contraceptive pill for ten years, the probability of getting breast cancer is not higher than that of women who never take the pill. Cervical cancer is mainly caused by the human Papilloma virus transmitted through sexual behavior. The contraceptive pill has no isolation function, and women who take the pill are generally sexually active, that is, they are high-risk groups of people infected with the disease, so it is easy to misunderstand the pill.

Myth 2: Contraceptive pills make people fat

According to relevant medical reports, there is no difference in weight gain or loss between women who frequently take birth control pills and those who rarely take them. The increase in women's weight is mainly due to lifestyle habits such as diet and sleep, as well as mental reasons such as anxiety, in addition to physiological reasons such as age.
