Are birth control pills prone to contraceptive failure? Is contraceptive failure related to symptoms?

For most young people today, the main effect of birth control pills is to kill sperm and interfere with the combination of sperm and egg, and many people have taken birth control pills for a long time without any failure, so everyone thinks that birth control pills will not fail. In fact, birth control pills may also fail. Most of the time, the failure of birth control pills is caused by not paying attention to this situation, so you need to be especially careful in normal times.

Oral contraceptives achieve the purpose of contraception by inhibiting ovulation

External contraceptives achieve the purpose of contraception by killing sperm. Since contraceptives are chemically synthesized drugs, if pregnancy occurs during the contraceptive process, both sperm and fertilized egg may be affected by the chemical effects of the drugs. Therefore, those who fail to use this method of contraception are best to have an artificial abortion to promote eugenics.

If you are taking emergency contraceptive pills, please read the following

Emergency contraceptive pills are for emergency use only and should not be used long-term. At present, no emergency contraceptive measures have been found that can be used routinely after every sexual intercourse, so conventional contraceptive methods are still important, such as condoms, intrauterine contraceptive rings, etc.

The pregnancy rate after failure of emergency contraceptive pills is 2% to 3%. If emergency contraception fails and pregnancy occurs, consultation can be sought based on whether or not one desires to have a child.

Those who have already given birth can arrange for medication or surgery to terminate the pregnancy. For those who have not given birth, it should be explained that the drugs generally do not cause fetal malformations. Within 1 week after fertilization, the fertilized egg has not yet implanted in the endometrium and is generally not affected by pregnant women's medication; 8 to 14 days after fertilization, the fertilized egg has just implanted in the endometrium, and the effects of drugs are not teratogenic except for miscarriage; 3 to 8 weeks after fertilization is an important stage of embryonic development, and various organs are differentiating and developing at this stage, and are most susceptible to teratogenic effects of drugs and the external environment. 8 weeks after fertilization, that is, 10 weeks after menstruation, all organs have completed differentiation, and the possibility of pregnant women taking medicine to cause teratogenesis is extremely small.

Emergency contraceptive drugs are often used around the time of ovulation and have little effect on the fetus. However, some women may take it after conception, so they need to consult a physician.
