Hello, No doctor should prescribe pills to induce a medical abortion at 16 weeks of pregnancy as this is not going to work. Technically, pills are used only until 9 weeks of pregnancy and preferably not beyond 7 weeks as the results are poor later on. In the current scenario, since you have used medication that is dangerous for the baby, you should go for an anomalies scan and decide whether you wish to retain the pregnancy or otherwise based on the result. The medications are teratogeneic, but, since you used them later in the pregnancy after the stage of organogenesis, fingers are crossed. Please see a specialist for further help as this is the only way out. Take care.
