Subchorionic hemorrhage?!

Samantha
So I went to the dr yesterday because of some light spotting and they found that I have a small subchorionic hemorrhage as well as placenta previa. I'm 11w 5d and since the ultrasound I've wiped twice and gotten heavier bright red blood. Is this normal? I thought maybe it could be because of the transvaginal ultrasound, but seeing that much really freaks me out!
