TW.... miscarriage. Help?

I would be 6w5d pregnant right now, but my pregnancy tests (even with diluted urine) have turned negative. Also, my symptoms went away about a week ago. I’ve been spotting for 5 days. I’ve been assuming I’m just going to miscarry, but now I think I should call my doctor? Because I’m not really bleeding yet. What will happen? If I don’t fully bleed? Would they have to do anything to help? I didn’t call when my tests went negative or when I started spotting because I didn’t really want to be pregnant right now anyway, and figured, I’ll just miscarry why do I have to tell the doctor about it? But now I think I’d better call, since it’s not coming away... but I don’t know what to expect. I thought it was going to be a chemical pregnancy and I would just bleed like a heavy period. But now that it’s a week later, I’m wondering if the miscarriage itself is going to be a lot more painful? Thoughts?
