Question About brown discharge...

My period ended on the 20th of August and I’m still getting brown discharge. It’s normal for me to have the black/brown blood at the end of my period. This is thick, slimy looking brown discharge. And it’s been going on for 12 days now. It smells but it’s not a fishy smell, and it’s different from the smell of my period.

I am sexually active with my husband.

I’m going to see a doc when I can, but it will likely be a couple weeks before I can.

Just wondering if anyone has had this or knows anything?

I can’t find anything online about brown discharge lasting so long...
