There are two kinds of unknown pregnancies. A denied, unknown pregnancy, graviditatas ignota, when the pregnant woman unconsciously denies the existence of the pregnancy. Contrary to the denied pregnancy there is a hidden pregnancy, a concealed pregnancy in women who know they are pregnant but actively hide their pregnancy from the family, partner, friends, teachers, colleagues, etc. The prevalence of an unknown pregnancy during the first 20 gestation weeks is 1 in 475 pregnancies, in the second half of pregnancy it is 1 in 2455 pregnancies and at the moment of delivery it is 1 in 7225.


A 40-year-old woman was transported by an ambulance and admitted to Gynecology and Obstetrics Clinic in Kragujevac after the delivery in home conditions and this patient found out about her pregnancy at the moment of delivery.


This case presents a classical example of a denied pregnancy. The reasons are probably at all levels, physiological, psychological and social. The patient was 40 years old, with two children aged 17 and 15 and irregular periods. Denied pregnancies present a multidisciplinary problem, which requires work of different specialties and services and this interferes with family and social life.


The denied pregnancy should always be taken into consideration in case of irregular periods, especially in perimenopause. Patients in perimenopause should have regular medical examination by their gyneocolgists, at least once in six months and the delivery outside hospital conditions that bears a great risk should be avoided at any rate.
