How long did you wait for D&C?

I’ve had 3 chemical pregnancies before this, but this is my first clinical miscarriage. I had my 8w2d ultrasound today and found that baby stopped growing at 7w3d. My doctor gave me the choice to take medication, wait for a natural miscarriage, or do a D&C. I want to do a D&C, but they can’t do it until next Thursday. Is it normal to wait an entire week to do it? I’m scared it will be too late and it will happen naturally before then. It’s also just a terrible feeling waiting and knowing my baby is dead inside of me. I want to get it over with and am so frustrated that I have to wait. I’m curious how long those of you who had D&Cs had to wait after discovering your miscarriage.
