These four contraceptive knowledge must be known by men and women to avoid accidental pregnancy

Feeling deeply and uncontrollably, it is essential to have sex with fish and water. However, in male and female sexual life, many do not understand some contraceptive knowledge, which leads to accidental pregnancy. Therefore, I do not want contraception to fail, and some contraceptive knowledge should be understood clearly in daily life, especially the following points. After all, accidental pregnancy requires abortion, which can cause great harm to women. What kind of contraceptive knowledge do you know?

1. Calendar-based contraceptive methods contraception is very safe

Most men and women will choose to have sex during women's Calendar-based contraceptive methods, that is, 7 days before and 8 days after menstruation. However, because of this method, countless people found that contraception failed, and the Menstrual cycle was irregular due to various factors, especially ovulation. It will be delayed in advance due to emotional, hormonal and other external factors. In addition, eggs will remain in the vagina for 1-2 days after being discharged, so the Calendar-based contraceptive methods is not as safe as expected, and its contraceptive effect is only 70%.

2. Breastfeeding sexual activity does not require contraception

Most women believe that they will not ovulate if they do not menstruate during lactation, so contraception is not necessary for sexual intercourse. However, this is a big lie. Breastfeeding is not 100% non ovulation, as long as there is ovulation, there is a possibility of pregnancy. It's just that some people haven't recovered due to physical reasons and haven't menstruated normally, so as long as they have sex, they need to take contraceptive measures.

3. Coitus interruptus can be both enjoyable and contraceptive

Some men believe that wearing a condom is uncomfortable, and women may also feel that it affects their sense of enjoyment. They may adopt extracorporeal ejaculation, believing that if sperm does not flow into the woman's body, they will not conceive. But in fact, external ejaculation is also an unreliable method of contraception. Although it can retreat in time every time, men will secrete prostate fluid when they are excited. This prostate fluid contains sperm, which will make women have a chance of pregnancy.

4. Frictional edges also prevent pregnancy

Most men and women believe that they will not get pregnant if they have no substantive life outside friction, especially if their hymen is not ruptured. But I don't know that although friction is not a sexual activity, it can cause men to secrete prostate fluid due to excitement during friction, and even cannot control ejaculation. Once it enters the vagina, the probability of pregnancy in women increases, and even virgins will enter through the gaps between virgins.

Kind reminder, there are many common contraceptive knowledge in daily life that women should understand clearly. After all, some blind beliefs can only lead to accidental pregnancy and harm. In addition, it should be noted that in addition to these points, sexual activity during menstruation is also not feasible. Although most women do not ovulate during menstruation, some women have irregular ovulation periods, and ovulation begins on the fifth to seventh day of menstruation, which can lead to conception. Moreover, even without pregnancy, it can cause significant harm to the female body, leading to endometriosis and other uterine inflammations.
