Antepartum haemorrhage
（重定向自Antepartum hemorrhage）
In obstetrics, antepartum haemorrhage (APH), also prepartum hemorrhage, is genital bleeding during pregnancy from the 24th week (sometimes defined as from the 20th week) gestational age to term.
It can be associated with reduced fetal birth weight.
In regard to treatment, it should be considered a medical emergency (regardless of whether there is pain) and medical attention should be sought immediately, as if it is left untreated it can lead to death of the mother and/or fetus.
