Period soon? 😭😔 period smell.

The facts: 8/29 miscarriage 10/19 d&c (it was incomplete miscarriage). I'm now 6 or 7 dpo and I ovulated like 4 days later than glow told me to and adjusted my period to 12/8 instead of 12/4

Every time today when I went to the restroom I swear I could smell that period blood smell. Multiple bathrooms, most with empty trashes. It was this overwhelming period smell but only when I dropped my drawers. I didn't even have a moment of spotting to justify this scent. Sorry if that was TMI but I don't understand why I would have that blood scent if I wasn't bleeding. This morning after I smelled it, I changed and washed and it still stuck around.

I've never had this before and its frustrating. I'm not even where I should be able to have a positive test let alone a period.
