I just found out im pregnant. ive been drinking tonic water w/ quinine and apple juice. would that have harmed my baby?

Hard to be sure: Therapeutic drug doses of the drug are considered risky & probably harmful during pregnancy. There is little information about the minimal amount contained in tonic water. If you have concerns about this pregnancy it would be reasonable to consult with a clinical geneticist, often affiliated with medical schools or children's hospitals. They could review all your risks in great detail.
