bleeding

I’m 6 days postpartum and this is my first so I’m new to this. I’m not sure if this could be related to my question, but I hemorrhaged to the point of being on the borderline of needing a transfusion, so I lost a good bit of blood. Anyways, I’ve always been told you bleed pretty heavy for 2 weeks and don’t stop completely until around 6. By this morning, I’ve already quit bleeding completely like not even a drop since 5 am. My stomach still looks like I’m 9 months pregnant & is as hard as a rock, I can still feel my fundus right below my belly button. I’m also still cramping off and on. Is this too early for me to stop bleeding? Should I call my doctor?
