10 weeks pregnant

So I’m 10 weeks now and had a scan at 8 weeks. They saw a pocket of bleeding which was away from baby. They said it should dissolve. However my last miscarriage ended because of a hematoma so I’m so scared I will lose this baby. I have a scan tomorrow. I’ve had no bleeding unlike last time, which gives me hope or is it still possible to miscarry without bleeding? I really hope the hematoma has dissolved tomorrow! 🙏🏻
