3 weeks post mc, still spotting?

I took pills to miscarry 3 weeks ago and the bleeding stopped after a week but I was told I had some debris left to pass so I took more misoprostol. The second dose didn’t do much besides start some light bleeding. Now for the past week I’ve had rusty colored blood and dark brown sticky discharge. It’s not a lot, just primarily when I use the bathroom and I only have to wear a panty liner. It smells the same as it’s always smelled and I’m not running any fever. Still pulling positive pregnancy tests but they are getting lighter.

Is this at all normal? I didn’t have this issue with my first miscarriage.
