Antepartum bleeding of unknown origin

In up to 2% of cases of APH, no cause or source of bleeding will be identified (78). While the patient can be reassured after the ini­tial assessment, the pregnancy should be followed up particularly if the APH is recurrent. These pregnancies are associated with an in­creased risk of preterm delivery and reduced birth weight babies and fetal death (78, 79). As a minimum, fetal surveillance with growth scans in the third trimester is recommended in cases of recurrent APH of unknown origin.
