Early pregnancies with unknowing chest x-rays, dental fillings, anesthesia or anti-inflammatory medications are not always unwanted, and most children can be kept after a thorough consultation and detailed counseling by a doctor. The use of medication during pregnancy is also a problem that often bothers women. The first thing to look at is the relationship between the medication and the time of conception. Usually, for women who have regular menstrual cycles of about 28 days, the effect on the embryo of medications taken within four weeks of the first day of the last menstrual period follows the “all-or-nothing” rule. Within four weeks of gestation, the embryo is still an undifferentiated cell mass that has not initiated the development of various tissues and organs, so if the embryocidal effect of the drug is large enough, spontaneous abortion will be triggered, but if the drug’s effect is slight, the strong embryo will be able to escape and will not suffer from any tissue or organ malformations or defects. From the 5th week of pregnancy, the embryo enters the stage of rapid growth and development, this is the extremely sensitive period of drug teratogenicity, the doctor will be classified according to the safety of pregnancy medication, the dose of medication taken and other factors, specific problems specifically analyzed, rather than a generalization, collectively recommended that women go to the abortion. High doses of ion rays can cause many serious injuries to the fetus, such as miscarriage, fetal growth disorders, cerebellar malformations, intellectual developmental disorders, and increase the risk of malignant tumors in children, but according to the American Radiological Society and the Society of Obstetricians and Gynecologists, the dose of irradiation of the fetus in the womb from the chest radiographs taken by the checkups is only 0.02 to 0.07 millirad, and it is only the doses higher than 5,000 millirad that can cause fetal damage. A single flat abdominal X-ray with a fetal exposure of 100 mrad and a mammogram with a fetal exposure of 7-20 mrad are safe and do not require abortion as an option. If multiple x-ray exposures are required, a radiologist should be consulted to calculate the total dose of exposure the fetus may receive and then make a decision. MRIs and ultrasounds have long been proven to be safe as an alternative or preferred choice during pregnancy, and both abdominal ultrasound and transvaginal ultrasound can be used safely and repeatedly during pregnancy. In our country, abortion is permitted by law, and medical care is obliged to provide abortion and induced abortion services as long as the mother applies for it. 28 weeks before, the life of the fetus is in the hands of the parents, and under such a national situation, parents should get professional and detailed advice before deciding whether or not to keep the fetus, and try their best to make a decision that is scientific, yet not forgetting the warmth of human nature and the preciousness of life, so that they will not harm the life of their baby, and will not leave their own life in danger. This is the only way to avoid harming the life of the child in the womb, and not to leave themselves with lifelong regrets.
