It is important to actively use contraceptive measures after having intercourse after taking Renqingmangjue, and oral emergency contraceptive pills can be given to prevent early pregnancy. Renqingmangjue is a traditional Chinese medicine that has the effect of clearing heat and detoxification and promoting gastrointestinal motility, but some of its ingredients have a certain effect on killing early embryos. If a woman becomes pregnant after taking this drug, it can easily lead to an increased chance of embryonic abortion and spontaneous miscarriage, so women should not take such drugs during pregnancy preparation. From the point of view of eugenics, it is better for a woman to stay away from bacteria, viruses and other unfavorable external factors during the preparation period, and to increase nutrition and strengthen the body’s resistance and immunity to facilitate a smooth pregnancy.
