How to do just a few days pregnant? Can I take medicine?

Hello, be sure to use medicine carefully and safely under the guidance of a doctor before pregnancy. The consequences of medication at different times are different: after fertilization 1 week, the fertilized egg has not been planted in the endometrium and is generally not affected by drugs; If the drug is taken within 1-2 weeks after fertilization, the fertilized egg has been implanted into the endometrium, but the tissue has not yet differentiated. The influence of drugs will not cause teratogenesis except that abortion is a safe period. Therefore, taking some drugs before pregnancy or early pregnancy will not have much impact on the fetus, so don't worry too much about induced abortion. 3-8 weeks after fertilization (menopause 5- 10), fetal malformation is easily influenced by external factors such as drugs, which is a "highly sensitive period of teratogenesis". During this period, drugs, including general health products and tonics, should not be used. If the drug can be used or temporarily stopped, it should not be used. If drugs must be used, they must be used carefully and safely under the guidance of a doctor. If the pregnancy continues, prenatal diagnosis (including B-ultrasound) can be made at 16-20 weeks of pregnancy.
