Whether drugs can be used in early pregnancy depends on what drugs are used and cannot be generalized.
Generally speaking, the early stage of pregnancy is a more sensitive period for the fetus, because the first 3 months is a critical period for the formation of the fetus, strictly speaking, you can’t use drugs, so as not to affect the fetus and increase the risk of fetal deformity, miscarriage, stillbirth and so on.
However, if it is necessary, such as severe vomiting in pregnancy, high fever, pregnant women with underlying diseases, etc., then you need to consult a doctor in a timely manner, and symptomatic treatment, under the guidance of the doctor to choose the drugs that can be used during pregnancy.
If you use drugs that are contraindicated or prudent during pregnancy, then you need to choose whether or not you need to continue the pregnancy based on your own needs and subsequent tests such as anomalies, prenatal counseling, and so on.
If there is any abnormality during pregnancy, it is recommended to consult a doctor for symptomatic treatment, and the use of specific drugs should be carried out under the guidance of a doctor.
