  To study the pregnancy outcomes in first trimester vaginal bleeding.

All women were evaluated for the outcomes including abortion, preterm rapture of membranes, preterm labor, second and third trimester vaginal bleeding, low birth weight and intra uterine growth retardation and the mode of delivery. Data were analyzed using SPSS- 11.
