Possibly a Subchorionic Hematoma

Am
Had a small episode of bleeding with a small clot last week, went to the ER(the baby was fine & had a heart beat measuring crown to rumb 6 weeks & 2days). Altho it was good to hear the baby was live and grown the spotting has been very stressful. Then about a few hours ago at 7 weeks & 3 days(today) a "big rush" of blood with a clot(no pain)came rushing out..first thing I said "I'm loosing my baby Omg!".. now its back to light spotting again. I go in for a ultrasound tomorrow & I'm going to also mention to carefully look for a Subchorionic Hematoma. I believe it has gone unnoticed & I need answers. Hope tomorrow my 😍blessing😍 heart💙 is still beating strong & is growing normally. I'm so emotional😦😔😢
