I had prepared all kinds of contraception beforehand, but I still had an accident and had to take remedial measures and take emergency contraceptive pills immediately. Why is the emergency contraceptive pill more reliable if it is taken within 72 hours after contraception failure?
Emergency contraceptive pills, as the name suggests, are a kind of pharmacological contraceptive remedies taken after having sex without contraception or contraceptive failure, with the purpose of preventing possible pregnancies.
The reason why women should take emergency contraception within 72 hours after contraception failure is that they wait up to 24 hours in the fallopian tube for the sperm's appointment after the egg is released, and up to 72 hours after the sperm enters the uterus. In other words, if ovulation and fertilization are successfully prevented within 72 hours to ensure that you do not get pregnant, of course, the sooner the better, otherwise the eggs and sperm have become fertilized eggs before taking emergency contraceptive pills works.
In addition, the initial effect of emergency contraceptive pills is to push back or prevent ovulation, so that the sperm misses the optimal waiting period and dies naturally. But if ovulation is delayed by 5 or 7 days, and you have sex again, if you think you have used emergency contraception and you can stop using contraception, you are making an important mistake and making the safe period the least safe.
Therefore, the correct use of emergency contraceptive pills must not only be used in the current month, but also should avoid unprotected sex before the next normal menstrual period. To put it in layman's terms, after using an emergency contraceptive pill, you have to use *** every time you have sex before your next menstrual period
It is necessary to clearly inform every female friend that emergency contraceptive pills are only a remedy and cannot be used as a long-term contraceptive method, otherwise it will not only cause contraceptive failure, but also may cause endocrine disorders and other problems, affecting women's health.
