MMC, maybe...

I was told on 11/2 I am miscarrying... I had only light light spotting and no clot passing or bleeding yet.. will I have to get a d&c what’s going on?? Capsule the doc just not have seen a sac? But why would my hcg drop?? I’m so confused and I just wanna start TTC again... I’m not bleeding so we have BD since Thursday... can I get preg again right now? Or does a lot of bleeding have to happen?
