Did the ultrasound confirmed the diagnosis of placenta
previa? If so, the bleeding is most likely due to the previa itself since the ultrasound was a transabdominal one and not transvaginal.
If you have placenta previa and are having vaginal bleeding
, please see or call your doctor immediately, as it may progress to preterm labor
, and you will need a c-section and other emergent medical care.
