Thrombocytopenia in pregnancy is a common finding. Although associated with the physiological processes of pregnancy, in moderate and severe cases of thrombocytopenia many pathological processes can cause it. Gestational induced thrombocytopenia is the first common cause for thrombocytopenia in pregnancy. Immune thrombocytopenic purpura is the second cause. It is hard to diagnose thrombocytopenia in pregnancy due to the lack of a single specific test to differentiate it, but with clinical and laboratory findings in the mother and infant, the diagnosis can be made. Some cases will be followed by the occurrence of thrombocytopenia in the babies. A 26 years old pregnant woman came with a chief complaint of fever 3 days before being admitted to the hospital.
