Pregnant women have experienced the use of medication without knowing it in the early stages of pregnancy. The impact on fetal development is not particularly large, do not need to carry out special treatment, you can continue the pregnancy, need to regularly do a good pregnancy test. Because since it has been used, the impact of the drug is not particularly large does not need to be dealt with through the method of vomiting, there is indeed a certain clear harm, you can vomit out the drug through the method of vomiting. In the early stages of pregnancy when the gestational sac has just formed, has not yet begun to obvious organ differentiation, this time the effect of drugs on the gestational sac is either yes or no. If the medication has already had an effect on the gestational sac, it may directly cause the abortion of the gestational sac. If there is no abortive effect, it will not lead to the abnormal differentiation of the fertilized egg, and will not cause fetal developmental deformities or other aspects of the problem. As long as there are no symptoms of miscarriage, the pregnancy can be continued, with regular pregnancy tests in the later stages to keep an eye on the normal development of the fetus.
