Her anxiety symptoms have regressed in clinical follow-up period. No obstetric problem during the pregnancy period and no clinical problem during the prenatal follow-up period was observed. Drugs were decreased gradually at the last month of the birth and the patient was followed up without all drugs in the last two weeks prior to the birth. Birth was by cesarean section on term and the birth weight of the baby was normal. His APGAR score was 5 and he has either respiratory or any clinic problem to be monitored in the couveuse.
