If you are pregnant with Chinese medicine, the effect on the fetus depends on two main aspects: one is the specific drug used, depending on whether the drug used is clearly toxic or absolutely not to be used during pregnancy, as well as the dosage of the drug and the duration of its use. Another aspect is the timing of the medication, when it was used and how many days it was used. Now there is a view that the drugs used within two weeks after ovulation are in line with the all or nothing phenomenon. All means that the drugs have a great impact and will lead to spontaneous abortion of the embryo; none means that the drugs have no impact and do not increase the rate of fetal malformation or miscarriage, and it is necessary to combine these two aspects to analyze them specifically to know if there is any impact on the fetus.
