Subchorionic hematoma

Bianca

Can anyone tell me what is considered a small hematoma or a large? I am 19 weeks tomorrow and I had a big rush of red blood on Saturday. Went straight to the ER and they told me the hematoma is 2 x 4.5cm. And that it appears to be in the middle region of the placenta. I dropped a picture of my report from the hospital if someone can help me out here. I’m freaking out. Thanks ladies!
