There is a popular saying that “a woman who is pregnant for less than three months will not be informed to the public”, which means that the early stage of pregnancy is prone to unstable fertilization of the egg and even miscarriage due to various factors, which is often referred to as unstable fetal image. Therefore, there are some aspects of early pregnancy that need special attention and necessary examination items. 1, general precautions: pay attention to rest, ensure sufficient sleep, keep a relaxed mind; diet should not be large fish and meat; avoid large movements, such as carrying heavy objects, strenuous exercise, prohibit intercourse; avoid colds and fevers, quit smoking and alcohol, refuse poison, do not contact with psychotropic drugs, such as colds need medication, need to consult a specialist, reduce exposure to radiation. 2, early pregnancy examination: women with regular menstruation and normal sex life should consult a doctor as soon as possible when they have menstrual periods, except for ectopic pregnancy at the first check. In addition, prenatal examination should be conducted at 6 weeks of intrauterine pregnancy, including physical examination, laboratory examination and ultrasound examination. Routine blood, urine, liver and kidney functions, blood glucose and thyroid function need to be checked for timely and effective treatment. In particular, abnormal blood glucose, such as diabetes combined with pregnancy, can be very harmful to both mother and child, increasing the risk of hypertension during pregnancy; for the fetus, a long-term hyperglycemic environment slows down its lung maturation and increases the risk of respiratory distress, lung infection and hypoglycemia after birth, requiring early treatment to control blood glucose; while low thyroid hormone levels (hypothyroidism), in severe cases, can affect fetal intelligence and bone development, with the risk of cretinism If the level of thyroid hormone is low (hypothyroidism), it may affect the fetus’ intelligence and bone development and risk cretinism. Echocardiography and ultrasound of the liver, gallbladder and spleen are also required to determine whether the pregnancy can continue and to assess the risk of the pregnancy. The current medical standard is that folic acid supplementation during the first 3-6 months of pregnancy can effectively reduce the possibility of neural tube abnormalities in the fetus, so folic acid needs to be taken before and during early pregnancy. For pregnant women who like cats, care should be taken to reduce exposure during pregnancy because cats may carry Toxoplasma gondii, which may lead to fetal toxoplasmosis. Pregnant women with specific medical conditions such as heart disease, hypertension, diabetes, severe obesity, and family genetic disorders need to be seen in a specialist or obstetrics high-risk clinic.
