Augmentin is a category B drug for pregnancy (which means it is presumed safe based on animal studies). The ear drops are category C (which is uncertain risk with no studies to prove adverse effects). Discussing these medications with your obstetrician is appropriate to make sure that you are not going to harm your child. From the exam, the physcian should have been able to see if you had drainage from the ear or if there was obvious infection. The antibiotics will not heal a perforation, only alleviate the infection and decrease any drainage...which is needed for the body to try to close the hole in your drum. Best wishes.
