One type of counseling that is often encountered in outpatient clinics is that after taking the morning-after emergency contraceptive pill and getting pregnant again, can I still have this child? This is actually a question of the use of drugs during pregnancy. The first two points to be clear about the use of drugs during pregnancy are the classification of drugs and the timing of the use of drugs. Some drugs can be taken by expectant mothers The majority of commonly used drugs can be classified according to the corresponding clinical data, giving a safety classification: A, B, C, D, X. Although pregnant, but not all drugs can not be used, if it is a class A or B drugs, or but use no harm; even if it is a class C drug, if necessary, it does not mean that it is necessarily contraindicated. Most commonly used medicines belong to category B or C. For details, you can read the instructions of the medicines, and you can also search the name of the medicine by using the “medication assistant” on your cell phone to see the classification of the medicines. Sometimes it’s okay to take the wrong medication Pregnancy is a long time, and the effects of medication at different times are different. Within 14 days of implantation If the drug has an effect, it will either act directly on the embryonic cells, causing the immediate death of the embryo, or it will not affect enough cells to have any serious consequences. Area of medical interest is known as an ‘all or nothing’ effect. So either you don’t get pregnant, or if you do get pregnant, then the medication had no effect. 14 days to 3 months This is the time when the systems are differentiating and if there is an effect, then it is the most teratogenic point. Therefore, it is generally believed that the first trimester of pregnancy is a sensitive period of teratogenicity; after 3 months, the differentiation of the systems is basically over, it is a process of development and growth, and the teratogenicity of this period has decreased. Taking birth control pills and getting pregnant? Emergency contraceptive pills, commonly used are synthetic progestins (usually norethindrone) such as “Yutting”, and also Mifepristone. Both are classified as Class X drugs. That is, they are clinically contraindicated if there is a definite pregnancy. However, in terms of timing, the usual time to take an emergency contraceptive pill is within 72 hours of intercourse, so either it has not yet implanted or has just implanted, so the effect on the embryo should be ‘all or nothing’ as mentioned above. That is, if the pill did not cause the embryo to die and abort, then there should be no serious consequences to the embryo. So, if you took the emergency contraceptive pill right after sex and ended up getting pregnant anyway, then it is possible to continue the pregnancy. However, in some people, the pill may be pushed back in time, or there may have been consecutive pills within a month, or there may have been unprotected sex before this pill as well. In these cases, the effect on the fetus is hard to say. Even if you are using the so-called “safe period contraception”, it is not safe and you may already be pregnant. So, be careful. I have heard that some people directly suggest abortion, which I think is a bit too hasty. In this country, it’s just too easy to suggest an abortion, and it’s arguably the least risky option for a doctor to directly suggest an abortion, but it’s still a life anyways. According to a study with a large sample, the chances of a baby born to a woman who took kynurenine before or after conception having a more obvious deformity was about 8.4%, which suggests that the drug is associated with birth defects, but that’s just a matter of probability, depending on how you interpret that ‘8.4%’. Therefore, the decision to keep or not to keep a child after taking birth control pills depends on the attitude of the man and the woman involved. In fact, since the thought of taking birth control pills, it means that they may not want to have a child, just that the contraception has failed, and they are afraid of the damage caused by abortion, so they have this kind of entanglement. Therefore, the most fundamental solution is not to take emergency contraceptive pills as a regular contraceptive method! What should I do if I accidentally take the wrong pill? Normally, apart from birth control pills, it is not uncommon to take the ‘wrong’ pill during pregnancy. For example, accidentally taking any antibiotic without knowing you are pregnant. My wife mistook a cold medicine for a vitamin during her first trimester. It’s not uncommon to see things like that. Many people will be very anxious, afraid that this mistake will affect the baby, and even want to simply abort it. In fact, during pregnancy really accidentally take the wrong medicine, do not need too much anxiety, you may want to check this medicine in the end belongs to which category. Usually, the commonly used cephalosporin antibiotics are class B drugs, are safe; commonly used cold medicine, if only occasionally eaten once or twice, rather than long-term use, generally are not a big problem. Therefore, if you accidentally use any medication during pregnancy, or if you are about to use any medication, don’t panic yet, please seek professional advice from your doctor, so that he or she can help you determine the possible effects.
