subchorionic hematoma help!!!

My doctor didn’t go into much detail about my hematoma. I am 9 weeks and I just found out I have a hematoma from getting an ultrasound. I just need some advice or I need others who can relate to my story. I don’t know if this is big or something to be concerned about. Like is the placement dangerous & could break where my baby is and cause a miscarriage? I just need experiences and advice. Im so worried and I need everything to be okay. I’m just a worried mess and I don’t know if this is bad or not at this point... I just want to know
