Many women of childbearing age go for X-rays when they are not feeling well or when their unit organizes a physical examination, only to find out that their period is late after the due date. When they go to the hospital, they are told that they have an unwanted pregnancy. This is both happy and frightening news! Why are they scared? It is because they will have a big question: Can they still have the baby if they have taken medicine or X-ray in early pregnancy? If you go to the hospital and ask the doctor, if you meet an irresponsible doctor, he will probably suggest aborting the baby without even thinking about it; if you meet a responsible doctor, he will usually think about checking the drug instructions, but Chinese drug instructions usually only indicate “prohibited” or “caution”. “The warning does not mean that the fetus will be deformed if the pregnant mother takes these drugs, but sometimes the doctor may directly advise the pregnant mother to abort the baby in order to protect herself from such warnings. Is this really the right thing to do? In fact, there is a lot of clinical evidence from abroad that the use of medication or x-rays in early pregnancy (note: this refers to the period before the 4th week of pregnancy, i.e. 28 days after the first day of the last menstrual period) can only have two effects on the baby in the womb: the first result is that the baby receives all the adverse effects and miscarries spontaneously; the second result is that the baby is not adversely affected and grows normally. The second result is that the baby is not adversely affected and grows normally. This is the internationally accepted “all or nothing” theory of early pregnancy. In other words, the use of drugs or X-rays before the fourth week of pregnancy will not result in the birth of a deformed baby, as is feared. This is because during the early stages of pregnancy (i.e. before the 4th week), the sperm and egg have just joined and are busy setting up camp in the uterus. At this time, the fertilized egg has only undergone simple cell division, increasing the number of identical cells, but it has not yet differentiated into different cells, tissues and organs, and since it has not yet differentiated into organs, it is not possible to talk about the formation of organ deformities, so it will not give birth to a baby with the deformities that people are worried about. In addition, the embryo has a self-correcting function during the process of cell division. If the cell division goes well, the fetus will grow up healthily, and if the cell division does not go well, the baby will be eliminated naturally. Many people, including some medical professionals, do not necessarily understand this, and once they hear that they have taken medicine or x-rays in early pregnancy, they suggest aborting the embryo, which has resulted in many human tragedies, and many pregnant mothers follow the doctor’s advice to abort the fetus for insurance purposes, but in fact the aborted fetus is a healthy one. Some people recover from the abortion and can conceive again, but others are very unlucky and will probably never conceive again. It is important to emphasize that in the case of an unplanned pregnancy before the 4th week of pregnancy, if the embryo has not been aborted spontaneously, the baby can be kept on an “all or nothing” basis. However, for couples who are planning or preparing for pregnancy, to avoid spontaneous abortion due to medication or x-ray, it is important to test for pregnancy before each medication or x-ray, and confirm that you are not pregnant before taking the x-ray. Also, to be on the safe side, you should avoid pregnancy for 3 months after the x-ray, including both men and women. The emergency contraceptive pill does not cause fetal malformation. Everyone will encounter this or that in life, take the matter of childbirth, some people want to have a baby, hoping all day long to get pregnant, sometimes even to take drugs to treat infertility, tossed for a long time the baby does not come; while some people do not want a baby, but the emergency contraceptive pill can not stop the baby to come to the door. In clinical practice, there are often women who take the emergency contraceptive pill after intercourse and still end up pregnant, so can they have the baby? Before answering this question, it is important to understand what the emergency contraceptive pill is. The main component of the emergency contraceptive pill is the progestin levonorgestrel (such as the well-known Yutin). These pills work by suppressing ovulation, preventing sperm from joining the egg, and preventing the fertilized egg from settling in the uterus. Its usage is to take one tablet (0.75 mg) as soon as possible within 72 hours after intercourse, and the second tablet 12 hours later; or two tablets (1.5 mg) together, and there is already a 1.5 mg emergency contraceptive pill on the market, such as gold yutin, which can be taken once. If vomiting occurs within two hours after taking it, you should take a refill immediately. People who get pregnant even after taking Yutin often suspect that they may have taken a fake pill, how can they still get pregnant after taking the pill? In fact, the success rate of these pills is not 100%, but around 80%, so there is still a 20% chance that a woman will get pregnant after taking these pills. If the medication does not succeed in suppressing ovulation, preventing the union of sperm and egg, or intercepting the fertilized egg in the uterus, then, according to the “all or nothing” theory mentioned above, the baby conceived in this case can be kept if it is not aborted. This theory sends a message to us: if you are not explicitly taking medication that is prohibited during pregnancy, do not take the decision to terminate the pregnancy lightly, but let nature take its course and wait and see what happens. This is because even if there is concern in case there is something wrong, it can be subsequently ruled out by means of medical detoxification tests. Nowadays, obstetric testing is quite sophisticated and can monitor fetal development through B-ultrasound, amniocentesis and various other tests. It is not too late to terminate the pregnancy in case any problem is detected in the fetus.
