Hello Rina Thanks for your query. I wonder if you were planning a pregnancy, why did you start the drugs without consulting first ? out of the drugs listed, two - triglimisave and arbitel are pregnancy category D. That means their use is prohibited in pregnancy and there is evidence of definite fetal risks if consumed. The other two are safer ones. At 7 weeks, you should now consult a fetal Genetics specialist, who would weigh your odds of having an abnormal child. Your age, family history, medical history etc would also influence the risk. The way ahead is fraught with dilemma, as there is no test that can assure you that your baby will be 100 % normal. Even in a normal natural pregnancy, some chance of anomalies always exist. Consult a Genetic Counsellor at the earliest and work out a way ahead. Take care
