Normal?

hello

I found out at my 8 week ultrasound there is no baby. A silent miscarriage called blighted ovum.

First test Nov 23rd

Second test Dec 23rd.

Does the line darken heavily like this for blighted ovum?

Shouldn’t my hcg be decreasing if there’s no baby?

I was told to schedule a D&C at my ultrasound appt.. just worried by my dark test.
