+*IVF
+*Bilobed placenta
--painless bleeding from fetal origin.
+==Evaluation==
+*Painless [[vaginal bleeding in pregnancy (greater than 20wks)|bleeding]] occurs during spontaneous rupture of membranes

-- mother's life not in danger
+==Differential Diagnosis==
--defect in placental formation- umbilical vessels travel through
