I assume your OB/GYN prescribed these drugs for you? If so, i'm sure he didn't think they would harm your baby but i do understand your worry b/c i too am a mother.Call the doctor and inform him that you have discovered this and talk to him about getting off of the medicine. Maybe there is something similar that he can give you. Have you stopped taking the medication since you discovered this? Have you already had an ultrasound to check that the baby was forming properly? If you are really worried, ask for him to perform another one to reassure you.
