I took birth control pills twice in half a month.

Taking birth control pills twice in half a month is a very dangerous practice, because taking birth control pills too many times can cause infertility. Female friends are advised not to take birth control pills more than once a month and no more than 3 times a year. Taking it twice in half a month can cause menstrual disorders and darkening of menstruation. Female friends should check the condition of the uterus to avoid infertility, and it is best to use condoms for contraception in the future.

Emergency contraceptive pills are an "emergency contraceptive" measure used after unprotected sex or when you realize that contraceptive measures have failed (condom rupture, slippage, missed contraceptive pills, etc.) to prevent unwanted pregnancy. There are two main types of emergency contraceptive pills. One is mifepristone tablets, with the trade name "Funel". Its advantage is that only one tablet needs to be taken within 72 hours after sexual intercourse, and the contraceptive effect is over 99%. Low-dose mifepristone is a new drug approved by the State Drug Control Administration for emergency contraception in the early 21st century. The other is levonorgestrel tablets, with the trade names "Yuting" and "Anting". Its characteristic is that two tablets are taken within 72 hours after sexual intercourse, with an interval of 12 hours. The contraceptive effect is over 98%. It has been used for emergency contraception since the 1990s.

1. Please do not take emergency contraceptive pills randomly

Emergency contraception refers to a contraceptive method used to prevent pregnancy within a period of time after unprotected sexual intercourse or contraceptive failure. Drug contraception is the most commonly used method.

Female friends can consider taking emergency contraceptive drugs if they suffer accidental injuries or have unprotected sex for other reasons, or if contraception fails, such as condom breakage, slippage, or incorrect calculation of the safe period. After excluding pregnancy, healthy women of childbearing age should apply the drug within 72-120 hours after sexual intercourse, but the failure rate is often higher if it is applied after 72 hours.

A commonly used type of emergency contraceptive is progestin alone, represented by Yuting. Each tablet of Yuting contains 0.75 mg of levonorgestrel. Take one tablet orally after sexual intercourse and another tablet 12 hours later. The chance of pregnancy after taking the medicine can be reduced to 1%-3%. Patients may experience mild nausea and spotting after taking the drug. Another type of emergency contraceptive is anti-progestin. [Copyright by Honglai Mall] The most commonly used one is mifepristone (each tablet has 3 dosages: 50 mg, 25 mg, and 10 mg). Take one tablet of any kind orally on the same day, and take another tablet after 12 hours. You need to fast for two hours before and after taking the medicine. The chance of pregnancy after taking the medicine can be reduced to less than 1%, with few side effects and some individuals experiencing changes in menstrual periods. If vomiting occurs within two hours after taking the medicine, the medicine should be vomited out and the same dose should be taken again.

There are a few points to note about emergency contraceptive drugs: First, emergency contraceptive drugs can only work for unprotected sexual intercourse this time, and the drug can only be taken once in a menstrual cycle. Other reliable contraceptive measures should still be taken during sexual intercourse after taking the drug in this cycle. Secondly, emergency contraception is only a temporary remedy and should never be used repeatedly as a regular contraceptive method. Third, if emergency contraception fails and the woman becomes pregnant, the incidence of neonatal malformations is high and the pregnancy must be terminated. Finally, I would like to remind everyone that emergency contraception should be carried out under the guidance of a doctor.

2. Why can’t you take too many emergency contraceptive pills?

Emergency contraceptive pills are an emergency contraceptive measure taken after conventional contraceptive methods have failed. They use a large amount of drugs to suppress the function of the ovaries and ovulation, producing a better contraceptive effect. Therefore, emergency contraceptive pills can only be used occasionally and in case of failure. If you want to use it as a regular method, taking this contraceptive pill repeatedly will interfere with women's ovarian function. [Copyright by Honglai Mall] We are currently observing the effects of repeated use of emergency contraceptive pills on women’s ovarian function. Theoretically, it will greatly interfere with ovarian function, so you should not take too many of them. In clinical practice, we encounter some young friends who always rely on emergency contraceptive pills. After using them once or twice, they will experience menstrual disorders. Menstrual disorders and changes in ovarian function are often difficult to treat.

3. Use of emergency contraceptive pills

NEW YORK (Reuters Health) - Emergency contraceptive pills may be effective for up to 120 hours after unprotected sex, new research has found.

Research by an international collaborative team shows that emergency contraceptive pills containing synthetic hormones can effectively reduce the risk of pregnancy from unprotected sex. It is generally believed that the pills are effective if taken within 72 hours after intercourse, but studies have found that they can be effective for up to 120 hours after intercourse. The earlier the pills are taken, the better the effect.
