Hello Ms. Hana,
I have gone through your query and congratulations on your pregnancy. As far as the medication you have consumed, there are no known teratogeneic effects reported and hence, you need not worry. Moreover, you had consumed very little dosage and that too, at a very early stage either just prior to after conception. In future, if you need to take any medication, do it after you take the guidance of your consultant. Please use folates and have a healthy diet and adequate rest. Hope this helps.
