Is it effective to have sex after taking emergency contraceptive pills?

Young couples nowadays often don't pay much attention to their sex life. In order to satisfy their momentary sexual desire, they will ejaculate without taking any contraceptive measures, which will greatly increase the chances of women getting pregnant. In order to avoid pregnancy, women will be asked to take emergency contraceptive pills. Some people have sex again after taking emergency contraceptive pills. So, is it effective to have sex again after taking emergency contraceptive pills?

First, will emergency contraceptive pills be effective if you have sex after taking them? Emergency contraceptive pills are ineffective after successful conception. If you have had multiple unprotected intercourse before taking emergency contraceptive pills, and the fertilized egg has successfully implanted in the uterus after the previous intercourse, emergency contraceptive pills will no longer have a contraceptive effect. That is to say, taking emergency contraceptive pills when you are already pregnant will not terminate the pregnancy.

Second, emergency contraceptive pills only protect against one-time intercourse. Emergency contraceptive pills can only work for unprotected sex that has already occurred once. Women who have unprotected sex again after taking the pills may still become pregnant. Therefore, you should not have unprotected sex after taking the medicine until your menstruation resumes. The effectiveness of contraception is related to the length of time between sexual intercourse and the use of the drug. The earlier the contraceptive pill is used after sexual intercourse, the better the effect. As the duration of taking the pill increases, the contraceptive failure rate tends to increase. Some women fail to use the drug according to the instructions in the drug instructions and take the drug for more than 72 hours.

Taking emergency contraceptive pills while taking other medicines. For example, during antibiotic treatment, contraceptives should not be used for contraception, because antibiotics can inhibit the reproduction of bacteria in the intestines, reduce the decomposition of hormone conjugates, and reduce enterohepatic circulation. Drugs such as penicillin and ampicillin can destroy normal bacteria in the intestines, reduce bacterial activity, and lead to lower concentrations of steroid hormones in the blood, which can lead to contraceptive failure. Note: Although there is still a chance of pregnancy after taking birth control pills, female friends should not worry too much about it, and should not think that birth control pills are ineffective, because generally speaking, as long as they are taken in the correct way, the chance of contraception can be 100%.
