Help talk me of a ledge

So I know this is going to sound crazy but here we go.

So I had a missed miscarriage at 11 weeks and a D&c September the 4th started having sex a week after not tracking anything just having fun. And as dumb as it sounds I just feel pregnant. But I’m terrified of taking a test and it being a false positive because of left over hcg.

What would y’all do??
