Vaginal Bleeding And Preterm Delivery

Vaginal bleeding during gestation is an ominous sign indicating an adverse pregnancy outcome. Bleeding can occur during all stages of gestation. It complicates up to 20% of pregnancies during the first trimester and is regarded as a sign of threatened abortion. During the second and third trimesters, vaginal bleeding was found to be a risk factor for adverse maternal and neonatal outcomes including preterm labor (PTL), preterm prelabor rupture of membranes (PROM), placental abruption, placenta previa, and stillbirth.
