No wonder your birth control failed. Look at what mistakes you made.

　　Contraception is an issue that modern menopausal men and women attach great importance to. If they don’t want to have children yet, contraceptive measures can save them a lot of trouble. But with so many contraceptive methods, why do some people still fall victim to it so easily?

　　1. Over-reliance on the so-called safety period

　　Girls generally have the habit of recording their menstrual periods, because they will go through an ovulation period (danger period) before, and then there will be a safe period, so many people choose to have sex during this so-called safe period in order to avoid using drugs and condoms. However, our menstrual period will be affected by some external and internal factors, so your safe period may become a dangerous period.

　　2. Contraceptive efficacy is affected

　　A. Food factors

　　Now there are many female Oral contraceptives are used to prevent pregnancy, and fertility can resume once the pills are stopped. It’s just that autumn is the time when grapefruit is on the market. If you eat grapefruit or citrus while taking the pill, it will greatly affect the efficacy of the contraceptive pill. If you do not take other contraceptive measures, the chance of unwanted pregnancy will greatly increase. Because they will affect the body's absorption and utilization of drugs, leading to contraceptive failure.

　　B. Drug factors

　　While taking contraceptive pills for contraception, taking some drugs that may affect the effectiveness of contraceptive pills may also easily lead to contraceptive failure, such as anti-tuberculosis drugs.； anti- epilepsy Disease drugs, detoxification and analgesic drugs, and hypoglycemic drugs will all affect the efficacy of contraceptive pills, which greatly increases the occurrence of accidents.

　　3. Improper use of condoms affects the effect

　　Condoms are also the most common way of life. This method of contraception does not require women to take pills and is relatively easy to use. However, if used improperly, it will still affect the contraceptive effect and make you accidentally infected.

　　A. 50% of people put it on too late or take it off too early

　　The condom we are talking about here is generally a male condom. What it means here is that you start wearing a condom after intercourse has been going on for a while, or you rush to take out the condom before it is over. It is said that 50% of people will make this mistake.

　　B. The condom has no sperm storage vesicle or is not deflated when used.

　　The sperm storage vesicle in the condom is to prevent the semen from flowing back after it flows out. However, condoms without this feature can easily expose the semen during the process. In another situation, even if there is a seminal vesicle, if the gas inside is not discharged during use, it still cannot be stored, resulting in semen leakage.

　　C. No inspection before use

　　Condoms are very thin, and 80% of people don’t have the habit of checking them before using them. If there are holes or damage inside, they will no longer be effective as a contraceptive. Also, if you use a sharp object to touch them when tearing them apart, it can easily cause holes in the condoms.

　　In addition, there are a few people who reuse condoms, some who start "working" in a hurry without fully unfolding the condom, and some who do not use lubricant and cause the condom to break during the process, or do not store it in the correct way, etc., all of which may affect the contraceptive effect.（99healthy Special article on the website (www.99.com.cn).
