Brown period after d&c??

HazelRose626
My d&c was 5 weeks ago exactly. Levels 3 days ago were 16. I think I'm starting AF but its brown? There's kind of a lot like a good amount more than just discharge, kinda mucusy, but brown. Is this the start of AF? I emailed my DR to ask, but thought id see if anyone had any insight. No pain, no bad smell
