Doctor was so weird

I had an miscarriage and my hcg levels drop to 5, now 4 weeks later I am pregnant again and she's talking about BC without even asking why I'm paying my cash to come see her, so I told her I'm pregnant again and she did a urine test and it's positive and she still saying maybe it's left over hcg from 11/26 MC.

First test I did at home on 12/18👆

Second test on 12/20👆

Third on 12/22👆

And she saw two dark lines on the test they have at the doctor office and she telling me about old hcg and BC 😧😧

She decided to get some blood drawn.
